摘　　要：为了选育高配合力水稻新恢复系,利用香稻/CDR22的F5代中间材料,与生产上强优势恢复系蜀恢527、明恢86聚合杂交,经多年异地选择,聚合多亲本优势基因,育成了水稻新恢复系黔恢785。该恢复系具有分蘖好、恢复力强、配合力高、花粉量大等特点,利用其配组的金优785、湘菲优785、两优6785新品种已通过贵州省审定,其中金优785获农业部超级稻认定;全优785完成南方稻区长江上游国家水稻区域试验,进入2014年审定程序。For the sake of breeding new restorer lines with high combining ability, the intermediate materials of F5 germination of the cross of rice/CDR22 were crossed by Shuhui 527 and Minghui 86, after years of selection in different places, a new rice restorer line Qianhui 785 was bred with more parents＇ dominant genes. This restorer line was of good tillers, strong resilience, high combining ability, a large number of pollens. The combination of Jinyou 785, Xiangfeiyou 785 and Liangyou 6785 were approved by Guizhou Agricultural Variety Approval Commission, the Jinyou785 was invested super rice by the Ministry of Agriculture; New combination of Quanyou785 completed the south area of Yangtze river upstream regional test, which would get into the approval procedures in 2014.
