Abstract:

Space mutation was a new technology of breeding. China's scientific and technological workers created a group of new rice germplasm, varieties and hybrid rice restorer line by space mutation. Fuhui 936 is a hybrid rice restorer line by space mutation and crossbreeding technology. It was bred by multiple cross of the restorer line Minghui 86 dry seeds after being carried by recoverable satellite / Tainong 67//CDR22. Ⅱyou936 was developed from the cross of good quality three-line male sterile ‘Ⅱ-32A’ with restorer line Fuhui 936. Its yield significantly increased by 10.82% compared with the control Shanyou 63 in 2 years the regional trial of Fujian province. Its resistance was stronger than Shanyou 63 to rice blast. Furthermore, its quality reached Grand 2 national good quality rice standard. II you936 has passed test by the crop variety approval committee of in 2005.This research could be successful in bringing out new varieties of high yield and fine quality hybrid rice.
