China's hybrid rice benefits the world

an unusual yard, the Hunan Hybrid Rice Research Center, next to a path in Dongmapoling, a city in Changsha, Hunan Province. The yard is not big, from the office building to the laboratory, and then to the exhibition hall, it is only a few minutes away. For more than 30 years, this yard has been the "holy place" of hybrid rice research in China.
Research Center, established in 1984, is the first professional research institution of hybrid rice at home and abroad. Several star varieties and breeding materials of hybrid rice were born here, reaching the highest level in the world of super hybrid rice research. Hybrid rice technology with fully independent intellectual property rights has made great contributions to food security in China and the world.Since the establishment of hybrid rice research in Hunan in 1964, the scientific and technological workers of rice breeding industry, represented by Yuan Longping, have made continuous breakthroughs in hybrid rice research, and achieved three major technological innovations from three systems to two systems to super hybrid rice.
- In 1964, Yuan Longping found "natural male infertility strains" in the early rice fields of Dongting. In 1966, Yuan Longping published his first paper, Male Infertility of Rice, in volume 17, Issue 4 of the Scientific Advisory. In 1973, china's three-series hybrid rice with success.
- In 1987, Yuan Longping proposed in his paper "Strategic Vision of Breeding of Hybrid Rice" that the breeding of hybrid rice should be divided into three stages of development, namely, the breeding process from the selection method into three stages of development, two systems and one system, and from the utilization of hybrid advantage level into three stages of development, namely, the breeding process is developing from breeding to simplicity and increasing efficiency. In 1995, a breakthrough was made in the research of hybrid rice in the two-system method, which can be widely promoted in production.
- In 1996, the Ministry of Agriculture of China established the China Super Rice Breeding Program. In 2017, the super rice variety "Xiang two excellent 900 (super excellent thousand)" Hebei 100 mu of the average yield of 1149.02 kg per mu, creating the world's highest rice yield.
Today, the third generation hybrid rice breeding technology has the advantages of "three-system method" breeding stability and "two-system method" distribution freedom, which allows our country to continue to maintain a world leading position in hybrid rice research.
data show that in recent years, China's hybrid rice cultivation area of 17 million hectares, accounting for more than 50% of the country
's total rice area; Yuan Longping said hybrid rice yields about 20% more than conventional rice, and the annual increase in grain production can feed 70 million people."I am very pleased to be able to help other developing countries develop hybrid rice to address food shortages." I firmly believe that by working together, my dream will come true in the near future. "At the end of June this year, the first China-Africa Economic and Trade Expo was held in Changsha, Hunan Province, and Yuan Longping
, who was in his late 90s, made a speech in English at a seminar on China-Africa agricultural cooperation and development, which instantly became popular on the Internet.
hybrid rice out of the country, began in 1979. At the time, the Department of Agriculture gave 1.5 kilograms of hybrid rice seeds to Western oil companies. When planted in the United States, these seeds yield more than 33 per cent more than local seeds. Next, china-U.S. hybrid rice technical cooperation continues to this day.
yuan Longping
, who has been invited to the United States five times to teach technology, remembers that western oil companies in the United States had come to China in 1981 to make a documentary, "In the Garden of the People's Republic of China - The Story of Chinese Hybrid Rice", which was shown on Japanese television nationwide and caused a stir.
Rice Technologies, which we work with, pays the research center an annual technology transfer fee. This year, the area under hybrid rice cultivation in the United States has increased again, accounting for 60% of the total rice cultivation area in the United States. Yuan Longping
said.
40 years, the range of hybrid rice technology has been expanding. Hunan Hybrid Rice Research Center and Yuan Longping Agricultural High-Tech Co., Ltd. held nearly 100 international training courses on hybrid rice, which trained more than 10,000 technicians for about 80 developing countries in Asia and Africa.
, hybrid rice is grown abroad in an area of 7 million hectares, with India, the largest growing area, having more than 2 million hectares. Yuan Longping said
hybrid rice not only solves the problem of Chinese food, but is also benefiting the whole world.years, Yuan Longping
, who calls himself "post-90", led China's rice research team to start salt-resistant rice selection and breeding technology, and achieved preliminary results.
that more than 6% of the world's existing land area is affected by saline. Of the arable land, 19.5 per cent of the water fields and 2.1 per cent of the drylands are already damaged by saline. In South-East Asian countries, millions of hectares of suitable rice-growing land are abandoned each year due to salinization. 15% of China's water fields are affected by salt damage to varying degrees. The global salinized land area is still expanding due to climate change, sea level rise, unreasonable drainage and irrigation systems, and underlying rocks rich in harmful salts.
" to start sea rice research and salt-alkali rice technology promotion, to achieve China's 'food in the ground, grain in technology', to ensure that 'China's rice bowl must be in their own hands' strategic objectives, are of great significance. China has 1.5 billion mu of saline land, of which about 200 million mu have the conditions for planting sea rice. The research of hybrid sea rice as one of the important directions of our future hybrid rice research can not only improve the area of hybrid rice cultivation in China, but also solve the problem of rice loss caused by seawater intrusion in Vietnam, Bangladesh and other countries.

Hunan Province, said.
