Yuan Longping led the super hybrid rice rush and rushed 1000 kg per mu

Following last year's super-hybrid rice production of a large area of ​​926 kilograms per mu, and the realization of the third-phase target in advance, this year, the scientific team led by Academician Yuan Longping has started the fourth phase of super hybrid rice with a large area of ​​1000 kilograms per kilogram. At present, in Nanyao, Sanya, Hainan, seed players who sprint for a target of rushing 1,000 kilogrammes per mu have been swept away to accept the selection.

At the Super Hybrid Rice Variety Test Field at the Hybrid Rice Research Center in Sanya, the seed contestants have entered the mature grain filling stage. After 20 days, they begin harvesting, and the crown, Asian and second runner-up competitions will soon be announced. These days, Yuan Longping, academician with a research team, went to the fields every day to check the growth of the players. The great wish of the great scientist who has passed the 80th year is to achieve the goal of producing 1000 kg per mu of super rice before he turns 90.

According to the introduction of academician Yuan Longping, super hybrid rice seed players rushing to produce 1000 kg per mu have their own "sauces". Among them, the newly-selected Guangzhan 63S/1128 two-line super hybrid rice has 500 grains per ear, each Thousand-grain weight of 30 grams, fertility rate is also above 90%, nearly 150,000 spikes per acre of effective rice ear, plant height of about 1.2 meters, is an absolute "little giant." The variety of this species has exceeded 960 kilograms per mu. This year, the predicted yield per mu in the Sanya Experimental Field can reach 1050 kilograms.

According to Academician Yuan Longping, the technical route to achieve the fourth-phase research goal has been determined. At present, at the Sanya Base, Academician Yuan Longping has invited experts from the nation’s biology and genetics to jointly study with the well-known domestic research institutes and universities including Wuhan University and Jiangsu Academy of Agricultural Sciences. He will map the genes of four crops with strong photosynthetic rates, such as corn and sorghum. Hybridization to super rice using biomolecule technology to further improve the high-yielding genes and capabilities of super rice. In the selection of research bases, Hunan has selected 4 counties including Longhui County and Zhangpu County as demonstration sites for the first batch of super rice with a large area of ​​over 1000 kg per mu.
