Troubled two-line super hybrid rice in China to promote the "curse" was finally Yuan Longping break. I recently from the National Hybrid Rice Research Center noted that the transformation of Science and Technology funds the project, "two-line hybrid rice yield 293 new combination of two excellent integration and promotion of efficient production technology," in Nanning, Guangxi acceptance of successful realization of two-line super hybrid rice in China Seed zero risk. Super hybrid rice in the family, the two priority 293 is the first super hybrid rice breeding to achieve the Ministry of Agriculture the second objective, which is a large area of the combination of 800 kg per mu. But little is known about the two excellent 293 "super mother" born very "delicate", wait on ill will "fight malaria," that is in the seed production season, when the extreme cold will encounter in booting from the seed set, cause the quality of super hybrid rice seed production is not high and can not be used. This world-class Yuan Longping has been plagued by problems for 18 years. Chief scientist of the project, China National Hybrid Rice Research Center Dr. Bai Delang told the author, two-line super hybrid rice seed production is most difficult to control the conversion and sunlight sterile line of the length of the precise relationship between temperature level. Risk resulting seed is super hybrid rice in large scale applications require capture of fatal bottleneck. 293 White DeLong excellent example to demonstrate in two two-line hybrid rice seed production risk. Rice crops are hermaphroditic, inbred seed generation seed. 293 is a super two excellent female parent "P88S" and the super-male parent, "0293" combination of birth of the "half-breed." In the seed process, "super mother" P88S pregnancy birth there are two possibilities: the average daily temperature of 24 booting above, with the flower stamens have "sex" no interest, the performance of completely sterile, which gives "eyeing "The neighbors 0293 to opportunity, bred" bastard "two excellent quality and superb 293. Following the temperature dropped to 24 , P88S stamens to partial recovery of fertility, birth to the "half-" two types of seeds, worse, those mixed with 293 hybrid seeds in two excellent self seeds infertile. In addition, the "super mother" exception in Earing In case of high temperatures, also due to "heat" to give birth rate. Super hybrid rice seed production base is very hard to find two excellent 293 for the Mozhun "temperament," research team led by Yuan Longping find suitable temperature Wuming County of Nanning City, 3,260 acres of contiguous large-scale rice seed is successful, this declared troubled two-line super hybrid rice in China to promote the "curse" to be hacked. 6 this month, Science and Technology Department of Hunan Province by the invitation of the Chinese rice expert on-site inspection and other authorities, the results show that the maximum 300 kg per mu, the average paid 236.2 kg per mu of dry valleys. This means that only from the seeds harvested seed base can be more than 100 mu of paddy cultivation, productive about 50 million kg of grain. Yuan Longping that with two-line hybrid rice seed production to guarantee zero risk, the world's food security problems have been just around the corner crack.
