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.
