Abstract: K-CMS through the "japonica / indica / / Indica" composite creation of hybrid rice sterile cytoplasm,to cultivate used in large-scale production,By Rice and Sorghum Research Institute of Sichuan Academy of Agricultural Sciences. It has a "three high and one low," the characteristics of: High rates of stigma, the stigma of high living, high-end of the morning to spend the accumulated rate and low rate of closed-ying. And in combination to improve co-ordination, setting rate, 1000-grain weight and outcrossing habits have very good results.
