Prof. Yuan Longping, Hybrid Rice and Local Ignoramuses
by Dr. MP Dhanapala
Some people are allergic to genetic improvement of crops. They are free to provide an appropriate technology to convince farmers to propagate and have their share of traditional crop species to lead a healthy life, ignoring the green revolution, improved crop species and use of agro-chemical inputs inclusive of plant nutrients.
I use the term “appropriate technology” to imply its feasibility, sustainability and economic viability from the farmers’ point of view. In this process, one should demarcate clearly between green revolution and green agriculture. The latter is yet ill- defined with no definite field tested technological recommendations for different crops developed or established.
Similarly, the sustainable agricultural enthusiast can engage in so called environment friendly non-toxic food production to feed the nation at an affordable cost. Surprisingly, the past cropping season (Maha 21/22) was deliberately ignored by the advisors and experts of sustainable green agriculture, without proper guidance and demonstrations to the farmers in all sectors of agriculture.
Everything was in a disarray and the responsible officers of the sector remained tight-lipped while securing their positions in office. Was this sustainable green agriculture? Are we to repeat the same? This needs an immediate and definite answer/solution before the Yala season begins in 2022. Farmers cannot proceed without well defined technological package.
To my mind, the agriculture we had until the first half of the 20th century was presumably sustainable and may have been green. The animal husbandry component together with farming systems and crop rotation, and sometimes the shifting/slash and burn cultivation system based on mixed-cropping associated with crop diversity were apparently considered Eco-friendly concepts in operation. But we failed to produce adequate food for the increasing population.
The land resources diminished gradually with more land being utilized to rear animals; then there was the population explosion. This situation led us to more intensive, demand-driven mono crop culture. Mechanization and other scientific innovations, inclusive of agrochemicals made good the acute shortage of labor as a result of people moving away from agriculture to white-collar jobs. This was influenced by education and urbanization.
How many of those who advise and insist on sustainable and green agriculture are prepared to engage in agriculture as their sole livelihood? Have they ever cultivated land to earn their livings? Probably not. But we have people from all sectors, including Buddhist monks (I am a Buddhist) promoting sustainable green agriculture with no strategies defined for successful implementation. They are unwilling to be full-time farmers. They preach and predict that in a few years’ time, agriculture would return to normal to feed the nation. They have no empathy with the farmers. This is the bitter reality.
The nostalgic eco-friendly scenario anticipated with sustainable green agriculture – forest cover, natural springs, unpolluted creeks and water bodies full of fish, soil microbes, flora and fauna etc. may well be only a dream that would not reappear on earth again. This lives in the minds of those who knew a more spacious era. We then had over 80 percent of forest cover in the country, Now it’s down to less than 30 percent with denudation of forests alongside the population explosion.
If we had the forest cover and a small population as in the past, then we could have continued life in a sustainable environment as we did centuries ago eating healthy food provided by nature. But now we have grown to a little over 22 million confined to 64.5 thousand square kilometers of land in an electronic age. We travel in carbon emitting limousines and supersonic aircraft consuming the resource of the earth without a care of what would happen the next day. Some of us only mark-time till we get the opportunity to migrate to greener pastures; but the poor and the incapable must continue to survive in this environment.
If one can supply the so-called healthy food at affordable prices for every inhabitant, then there is no necessity for a Green Revolution (not green agriculture) or Norman Bourlogue and his innovative approach to improve food production. We need food more than anything else, with the majority of our people born without silver spoons in their mouths.
The green revolution (not green agriculture) was brought about to produce more food for the increasing population within the country. Had we unlimited cultivable lands, the green revolution is meaningless as sustainable green agriculture was in place with rice and other field crops; but we were forced to improve productivity of crops within our limited agricultural land resource. This is the reason why the Norman Borlaugs of this world appeared. He was man who employed the modern plant type concept to improve productivity of wheat per unit area of land. This thinking migrated into rice and other cereal crops.
The modern Indica rice varieties were developed since the isolation of semi-dwarf rice mutant, Dee-Geo-Woo-Gen (DGWG), in Taiwan. There were two improved varieties, Taichung Native 1 (TN1) from Taiwan and IR 8 from the International Rice Research Institute (IRRI), introduced to Sri Lanka in the 1960s. But they failed to gain farmer acceptance. Sri Lanka too had a dwarf mutant of rice, K8 natural mutant (K8 nm), isolated at the Ambalantota Regional Rice Research Station.
K8 was known to be a sister-line of H4, the landmark cross-bred rice variety in Sri Lanka. The genetic improvement of rice in Sri Lanka was reported comprehensively in my newspaper article titled, “Rice Genetic Improvement Odyssey of Past Centuries” in the Sunday Island of 17/10/2021. This was to keep the misinformed or uncertain general public updated about the recorded historical developments of rice in Sri Lanka.
Some educated non-agriculturists distort the facts to convey to the general public that conventionally bred varieties were either hybrids or genetically modified entities. Probably the critics have forgotten the elementary Mendelian genetics they learned in “O Level” classes in schools. I invite attention of anyone who believes these critics to read the Sinhalese translation of the article titled “Are Modern Rice Varieties Genetically Modified Hybrids?” in page 11-17 in Govikam Sangarawa, 51 (2), June, 2020, Dept. of Agriculture..
Now, let me introduce Prof. Yuan Longping as the father of real hybrid rice. His contributions are in no way secondary to that of Norman Borlaug. He initiated the three parental hybrid rice technology to exploit heterosis/hybrid vigor to improve yield potential of rice and developed hybrid rice in China capable of out-yielding the conventionally cross-bred varieties by a substantial margin.
This procedure cannot be simply explained to convince the “local Longpings” who look at it without any background knowledge and experience in floral morphology and genetics of rice. Some of Prof. Longping’s “Super Hybrids” are capable of yielding 18 t/ha (360 bushels/ac) in high potential environments. Though he left us nine months ago and is not with us any more, Prof. Longping admitted that conventionally bred varieties in such specific environments are capable of yielding 16 t/ha (320 bu/ac).
I have listened to this statement of Prof. Longping on two occasions while answering a question raised by the IRRI hybrid rice breeder, Dr. Sant Virmani. Our national average yields of conventionally bred varieties are slightly below 5 t/ha (100 bu/ac) within the country, but I am confident that ours too can reach the potential of above 15 t/ha (300 bu/ac) or more in a matching environment.
The limiting factor is the potential of our environment; the edaphic (soil) and climatic factors specifically. Those who are misinformed that the conventionally bred (cross-bred) varieties are hybrids, can visit RRDI, Batalagoda to learn the breeding process of hybrid rice. The major constraints associated with the program are development of perfect cytoplasmic male sterile parent (A line) and its maintainer parent (B line); fertility restoration parent (R line); standard heterosis or pronounced hybrid vigor and the enhanced cross pollination capacity between the A and R lines (the rice plant is a hermaphrodite and an obligate inbreeder (cleistogamy); seed production process in isolation (space or time) without contamination and finally the unwarranted criticism by the local Longpings.
Now, we in Sri Lanka inclusive of all the local Longpings, can taste hybrid rice from China. All or some of the one million tons of Chinese rice to be imported shortly have to be hybrids, as more than 60 percent of the Chinese rice crop is from hybrid rice. Although one can conveniently avoid answering the questions in the media about the cultivation process (green or non-green), the yield potential of hybrid rice cannot be realized through sustainable green agriculture; it has to be some form of non-green agriculture involved in the process of commercial rice production in China.
The health-concerned local Longpings can investigate and compare the status of Cadmium (Cd), Arsenic (As) and Lead (Pb) and verify the quality and suitability of the imported rice for consumption by the general public. I am inclined to consume it any way, as I am from the farming community and confident that no Chinese can survive without kidneys.
I have expressed my gut feelings about the non-green rice cultivation advocated during my tenure in office at the Rice Research and Development Institute (RRDI), Batalagoda, in the newspaper article titled “Expert Advisor, Sustainable Farming and the Rice Farmer”, Sunday Island of 07/11/ 21. After serving 31 years at Batalagoda, with my family living with me and consuming non-green rice and other food items, we have suffered no ill effects. This is a real life experience.
Unfortunately the facts are being distorted by critics to their advantage. Accuracy and precision are two key words in scientific statements. In my newspaper article titled “Beyond Illusion to Reality with Traditional Rice”, Sunday Island of 10/10/2021, I have highlighted this fact as some conclusions were arrived at when evidence is inaccurate and incomplete.
Recently, in a U-tube discussion, the resource person was very confidently elaborating that Carbon and Nitrogen were subjected to pressure in the synthesis of urea and in the process Cadmium and Arsenic appear as contaminants. Is this how urea is synthesized? How come that something not in the raw material appears in the ultimate product? Also, in the same program, the resource person insisted that thunder showers make nitrate from atmospheric nitrogen and that is adequate to raise the rice crop in the field.
I knew nitrate as a negatively charged ion (NO3-), but not as a chemical compound called nitrate, and the lightening process will produce nitric acid (HNO3) identified in Sinhala as “Akunu Wathura”. (Plants grow better during rainy days irrespective of thunder showers. Here, the confounded effects of many factors are involved in the process. Availability of Sulphur in the form of Sulphur Dioxide (SO2) is reported from rain water analysis locally, but one can quantify the availability of adequate N in rain water in the form of any nitrogenous compound, by analyzing the rain water in March/April, the peak period of lightning and thunder showers.)
The media person in the program was patiently listening to and admiring the resource person. This reflected on his quality and knowledge more than the inaccuracy and the lack of precision of the two statements. Many unscientific and inaccurate statements of this kind may seep into society and get registered in the minds of laymen if the media is negligent, incompetent or qualified to do their job properly. The most sensible and rational strategy to come out from the present fertilizer dilemma in rice cultivation is suggested in the write-up “Are We Making Rational Decisions in the Rice Sector?”, Sunday Island of 12/09/2021.
Scientists never lie or distort facts to their advantage. If it happens, he is not fit to represent the scientific community any more. Prof. Yuan Longping was a dedicated scientist of extremely high caliber. Moreover, he was a very humble, down to earth gentleman. He made somethings happen that the rice scientists thought was extremely difficult, if not impossible. This would be appreciated only if you understand the morphology (hermaphroditism) and pollination mechanism (cleistogamy) of the rice floret (spikelet).
Prof. Yuan Longping’s hybrid rice research was immensely supported by the government of China. That made hybrid rice a reality by making its cultivation mandatory to some extent. Chinese understand the value of research. Hybrid rice is apparently the ultimate technological innovation or climax in rice breeding, if we are to protect ourselves from hunger.
It is too early to execute hybrid rice cultivation in our country as we need further research to confirm its practicability within our infra structure. However, our Longpings are protesing against hybrid rice at the outset itself, even prior to the development of hybrids without understanding the real mechanism underlying the breeding process. That is the difference between progressive and stagnating nations, probably governed by inherent genes.
I will conclude this disclosure quoting Prof. Yuan Longping, “The ship (hybrid rice) is always above the surface of water (conventional varieties)” i.e. when you improve the potential of conventional varieties, a hybrid can be developed to surpass the yield potential of that variety.

State Banquet Hosted by the President for the Maldivian President and Delegation
A special state banquet hosted by President Anura Kumara Dissanayake in honour of Maldivian President Dr Mohamed Muizzu, who is on a state visit to Sri Lanka at the invitation of the Sri Lankan President, was held on Monday (04) at the President’s House in Colombo Fort.
Upon arrival President Dr Mohamed Muizzu and First Lady Sajidha Mohamed were warmly received by President Anura Kumara Dissanayake.
Addressing the gathering, President Dissanayake stated that the long-standing and steadily growing close relationship between Sri Lanka and the Maldives has been further strengthened by the visit of President Muizzu and First Lady Sajidha Mohamed.
He also noted that if the unique appeal of both nations could be jointly promoted, it would bring significant benefits to the people of both countries, particularly in the tourism sector.
The President further emphasised that the strong ties between the people of Sri Lanka and the Maldives, along with their cultural connections, date back centuries. He added that similarities between the two languages reflect this bond, and that the two nations will continue to remain close friends engaged in constant interaction.
President Dissanayake remarked that Sri Lanka considers it an honour to have hosted the signing of the Maldives’ Declaration of Independence in 1965, describing it as a symbol of unity, cooperation and goodwill between the two countries. He added that this is why Maldivians regard Sri Lanka as their second home.
He also stated that the Maldives is regarded as a reliable and valuable partner in efforts towards Sri Lanka’s social and economic development, as well as regional peace and prosperity, highlighting the importance of joint engagement on global issues.
Pointing out that the two countries, as neighbours in the Indian Ocean, share deeply interconnected realities, the President said that challenges such as rising sea levels, climate change and global economic crises affect both nations. He stressed that these can only be addressed through unity and collective purpose, and expressed appreciation for the Maldives’ support during times of difficulty in Sri Lanka.
He further noted that the discussions held between the two leaders would open new avenues for strengthening cooperation between the peoples of both countries. Inviting President Muizzu to work together in safeguarding enduring values such as tolerance, compassion and sustainability, he emphasised the importance of unity in building a brighter future.
Extending his best wishes to President Muizzu and the Maldivian delegation, President Dissanayake expressed confidence that the visit would contribute to the continued progress and prosperity of both nations.
In his address, President Mohamed Muizzu stated that it was a great pleasure to visit Sri Lanka, a long-standing partner in Maldivian history. He described the occasion as not merely a diplomatic engagement, but a celebration of a friendship as deep and gentle as the ocean that connects the two island nations.
He noted that for centuries, the waves between the two shores have carried more than trade and travellers, they have conveyed trust, affection and a shared rhythm of coexistence without rivalry, built on cooperation.
President Muizzu described these enduring human bonds as a golden thread uniting the two nations, characterised by humility, sincerity and permanence.
He emphasised that the friendship between the two countries is founded on mutual respect and has successfully withstood the tests of time. He recalled that Sri Lanka has always extended a steadfast hand of friendship to the Maldives, and expressed the gratitude of the Maldivian people for Sri Lanka’s support in shaping and nurturing the nation’s development.
He further stated that the ocean does not divide Sri Lanka and the Maldives, but unites them, adding that their unity is their greatest strength in ensuring that the Indian Ocean remains a region of peace, stability and opportunity for all.
Addressing climate change as a pressing global challenge, President Muizzu called for joint advocacy for climate justice and for the rights of small nations to survive and thrive. He stressed the importance of collaboration in innovation, resilience and global dialogue, noting that the true meaning of diplomacy lies in the people of both nations.
He also acknowledged Sri Lanka’s achievements in literacy, healthcare and human development as a long-standing inspiration to the Maldives. Looking ahead, he expressed a desire to deepen ties through opportunities in education, training and technology that empower younger generations.
He highlighted that every student nurtured, every life healed and every mind inspired contributes to a more peaceful and prosperous region.
President Muizzu remarked that Maldives–Sri Lanka friendship is not only recorded in official statements, but lives on in the smiles of children growing up familiar with each other’s flags, languages and cuisines. He noted that such bonds are reflected in the warmth exchanged between citizens and the quiet pride shared in each other’s success, adding that these connections cannot be artificially created, they must be experienced and cherished.
Concluding his speech, he stated that although the horizon may be vast, it always unites the sea and the sky, just as the Maldives–Sri Lanka friendship, though far-reaching, is always grounded in shared purpose and mutual respect.
He invited both nations to move forward together with gratitude for the past, confidence in the present and hope for a shared future, expressing his wish that the close friendship and cooperation between the Maldives and Sri Lanka will continue to grow stronger.
During the event, President Muizzu also signed the official commemorative book for visiting heads of state.
Several Sri Lankan dignitaries, including Prime Minister Dr Harini Amarasuriya, Deputy Speaker Rizvie Salih, and other ministers and officials, were present. Members of the Maldivian delegation, including senior ministers and diplomatic representatives, also attended the occasion.

India pushes for direct link between Rameswaram and Talaimannar, FTA upgrade
India wants to upgrade the India-Sri Lanka Free Trade Agreement, signed in 2000 during Chandrika Bandaranaike Kumaratunga’s presidency.
Declaring that more than 65% of Sri Lankan exports use FTA benefits whereas only 5% of Indian exports use the same, Indian High Commissioner in Colombo, Santosh Jha, emphasised the urgent need to transform the FTA into a modern framework that delivers the full potential of the bilateral economic partnership.
Jha was addressing the Global Innovation & Leadership Summit “Sri Lanka & India Ties: A Civilisational Bond,” organised by Z Media & WION, in Colombo, recently.
Jha said: “We have spent too long talking about it (FTA); sometimes renaming it; but not actually moving with purpose and required political will to forge a new framework. I say this not to assign blame — but to note that every year of delay is a year of opportunity lost. Think of it, in the last six years, India has signed nine FTAs, covering trade with 38 countries.”
Jha dealt with the situation developing in West Asia where the unprovoked US-Israeli war against Iran has caused tremendous hardships all over the world.
“We are living through an extraordinary period of global turbulence. Supply chains, markets, and everything else available, as a leverage, are being weaponised, as never before. Geopolitical competition is reshaping trade, alliances and partnerships. Trust in global order is eroding; Utility of global institutions are in question. Wars and conflicts are proliferating; even if these wars are regional, nobody seems immune from its impact. Economic uncertainty in some form or another has become almost a permanent condition. And we are all struggling in different degrees to adapt, as nations.
In these circumstances, relationships built on shallow transactional foundations are the first to crack. They are the ones where a change of government, a shift in commodity prices, or a geopolitical tremor is enough to undo years of effort.”
Commenting on Indo-Lanka relations, Jha said: “Civilisational bonds are different. They are not dependent on who happens to be in office in any given year. They are not contingent on a favourable deal or a transaction. They are sustained by something far deeper and more durable: a shared sense of who we are and where we come from, and what we seek to build for ourselves.
When the world is uncertain, you turn to those you trust. And trust, real trust, is built over centuries, not decades. India and Sri Lanka have that in plenty. But we must not take it for granted. In fact, we should nurture it, build on it and use it to our mutual advantage.”
Jha underscored the need to connect India with Sri Lanka. Jha said: “Let me be direct. The distance between Colombo and Chennai by sea is roughly 300 kilometres. But the distance between Rameswaram and Talaimannar — the closest points of our two countries — is about 30 kilometres. Thirty kilometres. And yet, there is no direct road. No railway. No ferry service that runs at scale. No energy grid connection. No pipeline. It is, frankly, an anomaly. It is as if two neighbouring rooms are connected only through a corridor outside, even when there is a door that can be built between the two rooms, right in the shared wall of the two rooms. We need to open that door.”
Land connectivity via a bridge or tunnel across the Palk Strait has been discussed for decades. There are enough examples of such corridors across the world. The engineering is well understood. The economics are compelling. The benefits, wherever such bridges have been built, are unmistakable. But we continue to waver. But let me say clearly: the time for wavering is over. A fixed link between India and Sri Lanka would transform the economic geography of this entire region. It would make Sri Lanka a hub, it aspires to become, in a way that no port expansion or airport upgrade can achieve on its own.
Energy connectivity is equally transformative. India has made massive strides in renewable energy across solar, wind, nuclear and green hydrogen. Sri Lanka has its own targets. A submarine electricity interconnection between the two countries would give Sri Lanka access to affordable and clean power. It will also create a market for Sri Lanka’s energy exports and help realise its vast potential. In a power-hungry age of data centres, India’s demand for renewable energy will only increase; and Sri Lanka needs to fully understand that opportunity to forge ahead.
Beyond electricity, serious conversations must also take place about long-term energy supply arrangements, including the petroleum pipeline and the development of tank farms in a meaningful, sustainable way. It can provide Sri Lanka with price stability and energy security. Something that we know today after the West Asia crisis is at premium. These are not fantasies. They are projects that have been studied, scoped, and in some cases are ready for decision. India already has implemented similar projects with its other neighbours – Nepal, Bhutan and Bangladesh – who are benefitting not just by exporting their surplus power to Indian markets but also by enjoying a level of energy security, which would not have been possible otherwise in the current difficult global situation.

Treasury theft won’t be treated by creditors as a default: Govt.
Sri Lanka’s creditors were unlikely to classify the recent USD 2.5 million Treasury fund heist as a technical debt default, Deputy Minister of Finance Anil Jayantha Fernando told Parliament yesterday (05), citing assessments by the Government’s financial and legal advisors engaged in the debt restructuring process.
Responding to queries raised by Opposition Leader Sajith Premadasa, Fernando said the incident is expected to be treated as a cybercrime matter rather than a failure or refusal by the State to honour its debt obligations.
“Although the funds remitted by Sri Lanka were not received by the Australian creditor, this does not indicate an inability or unwillingness on the part of the Government to repay,” he said, adding that given the nature of the incident and Sri Lanka’s relations with Australia, advisors believe neither Australia nor Paris Club members are likely to deem it a debt default.
Fernando said debt restructuring advisors had been consulted on whether the episode could amount to a technical default, while investigations are continuing to establish the nature of the alleged fraud.
Outlining the sequence of events, he said the Sri Lanka Computer Emergency Readiness Team was notified on January 9, 2026, with the Criminal Investigation Department also informed the same day. He said Australia Export Finance later notified Sri Lankan authorities on March 23 that the funds had not been received. A complaint was subsequently lodged with the CID by the Director General of the External Resources Department on March 24, while the Financial Intelligence Unit was informed on April 1.
Rejecting allegations that the Government had withheld information from Parliament, Fernando said there had been no attempt to suppress facts, noting that disclosure had been delayed pending further clarity from ongoing investigations, particularly regarding possible official involvement and internal control lapses.
He assured that all findings would be presented to Parliament in due course.
Premadasa questioned the delay in informing the House, given the timeline of events.
Fernando also cautioned against unverified speculation surrounding the death of a Ministry official linked to the incident, urging both the Opposition and the media to refrain from disseminating unsubstantiated claims.
Responding to claims raised by Premadasa that the deceased official was the first to detect and report the fund diversion, Fernando declined to confirm or deny the assertion, warning that such speculation could mislead the public and aggravate the situation.
He said investigations by the CID, in collaboration with the Finance Ministry’s External Resources Department and the Public Debt Management Office, are ongoing, adding that the continued service of the Ministry Secretary would not impede impartial inquiries.
“I am not prepared to present unverified information until investigations are concluded,” he added.
