-
摘要: 明恢86是福建省三明市农科所育成的集恢复力强、恢复谱广、配合力高、中抗稻瘟病、米质优、再生力强等特点于一体的超级稻恢复系。到2010年止,全国以明恢86为父本配组育成了11个组合通过省级以上品种审定,其中3个组合通过国家品种审定,1个组合被农业部认定为超级稻组合。从1997~2010年,用明恢86配组的所有组合累计推广面积达221.13万hm2。明恢86还是选育新恢复系的重要骨干亲本。到2011年止,全国各育种单位以明恢86为亲本选育的新恢复系有44个,这些新恢复系配组了65个组合通过省级以上品种审定,其中5个组合被农业部认定为超级稻组合。从2004~2010年,这些恢复系配组的组合累计推广面积达131.27万hm2。最后分析了明恢86所配组合的超高产特性。Abstract: Minghui86 was an Indica restorer line for super hybrid rice developed by Sanming Research Institute of Agricultural Sciences, Fujian province. It is characteristics of broad restoring spectrum, strong restoring ability, high combining ability, medium resistance to rice blast, high grain quality and strong ratooning ability. Up to 2010, there were 15 combinations of hybrid rice approved by the national and provincial crop variety registration committee, four of them were approved by the national authorities in China, one of them were regarded as super hybrid rice by the Ministry of Agriculture of China. The data indicated that the total extension area of hybrid rice combinations derived from Minghui86 was 2. 211 3 million hectare. Furthermore, Minghui86 was am important backbone parental to breed new restorer lines. Up to 2011, 44 new restorer lines were bred successfully derived from Minghui86 as the main parent in China. 65 combinations of hybrid rice derived from these new restorer lines were approved by the national and provincial crop variety registration committee. The total extension area of hybrid rice combinations from these new restorer lines derived from one of parent Minghui86 was 1. 132 7 million hectare in China from 2004 to 2010. Finally, the anthor analyzed on super-high yielding character of hybrid rice combinations derived from Minghui86.
