Yuan Longping, widely known as 'the Father of Hybrid Rice,' died of illness in Changsha at 1:07 p.m. on Saturday at the age of 91, according to the Xinhua News Agency.Yuan, the pioneer of the research and development of hybrid rice in China, was the first scientist in the world to successfully utilize the heterosis of rice.On September 29, 2019, on the eve of the 70th anniversary of the founding of the People's Republic of China on October 1, 1949, Yuan was awarded the 'Medal of the Republic'. The award speech stated that he had devoted his life to the research, application and promotion of hybrid rice technology, created a super hybrid rice technology system, and made outstanding contributions to China's food security, agricultural scientific development and world food supply.Yuan, born in September 1930, hadhelped China work a great wonder feeding nearly one-fifth of the world's population with less than 9 percent of the world's total land.Getting enough to eat, however, used to be a serious problem in China. 'I saw heartbreaking scenes of people starving to death on the road before 1949,' recalled Yuan.It was in that year that Yuan applied for Southwest Agricultural College and began his special connection with rice a staple food for many Chinese people that would become the focus of his lifelong research career.A discovery of a peculiar wild rice species by Yuan in the southern island of Hainan in 1970 became the prelude of China's decades-long effotrts of hybrid rice research. Three years later, he cultivated the world's first high-yielding hybrid rice strain with three lines, namely, the male sterile, maintainer and restorer.Hybrid rice has since been grown across the country and farmers have reaped incredible output after switching to Yuan's hybrid varieties.Hybrid rice recorded an annual yield about 20 percent higher than that of conventional rice strains meaning it could feed an extra 70 million people a year. Now its accumulated planting area in China has exceeded 16 million hectares, with the total grain output reaching 658 billion kilograms (kgs) in 2018, a nearly fivefold increase from that of 1949.In 1986, Yuan brought up the hybrid rice breeding strategy from the three-line hybrid rice strain to a two-line, and later on to a one-line variety. The two-line technique means that the hybrid rice seeds are cultivated with the male sterile and restorer lines only, which will call for less complicated techniques, save labor and cut costs. Compared with its three-line predecessor, the two-line hybrid rice strain has higher yields and makes use of manpower and material resources more efficiently, according to rice experts.Yuan's team has continued to make new breakthroughs. The team was invited to make a trial plantation of the saline-alkaline tolerant rice in experimental fields in Dubai in January 2018, and it was another success story for the team. China's export of saline-alkaline tolerant rice and the technique has been eyed as a way to combat the world's food insecurity.In 1995, local farmers planted 20,000 hectares of two-line hybrid rice in 55 counties on a trial base. The per hectare output reached 8,250 kgs, 1,125 kgs more than that of the three-line strain. The success established China's leading position in the global field of hybrid rice research.
