明恢82是福建省三明市农科所育成的早熟、抗瘟恢复系,该恢复系的育成与应用对进一步拓宽福建省早熟恢复系的遗传背景,实现抗性基因多元化,并进一步提高杂种优势,提升产量水平和改善稻米品质,满足福建省水稻生产对早熟杂交水稻组合的不同需求发挥了重要作用。至2010年,全国以明恢82配组育成了6个组合通过省级品种审定,用明恢82配组的所有组合累计推广面积达60万hm2,累计增产粮食3.49亿kg。明恢82还是选育早熟恢复系的骨干亲本,至2010年,全国各育种单位利用明恢82先后育成了5个新恢复系,其所配组的组合有6个通过省级以上品种审定,其中1个组合通过国家审定。最后,笔者还分析了明恢82在生产上能够大面积应用的原因。

Minghui82 was an early maturing and disease resistance restorer line for hybrid rice developed by Sanming Research Institute of Agricultural Sciences of Fujian province.It played an important role in broadening genetic background of early maturing restorer lines,realizing resistance gene diversification,improving heterosis level,increasing yield,improving rice quality and satisfying different demands of the early maturing hybrid rice in Fujian province.Up to 2010,there were 6 combinations of hybrid rice approved by provincial crop variety registration committee,and one of them was approved by the national authorities in China.The statistics indicated that the total planting area of hybrid rice combinations derived from Minghui82 was 600 thousand hectare,the output of rice increased by 349 million kilograms.Furthermore,Minghui82 was am important backbone parental to breed early maturing restorer lines.Up to 2010,5 new restorer lines were bred successfully derived from Minghui82 as the main parent in China.6 combinations of hybrid rice with these new restorer lines were approved by the national and provincial crop variety registration committee.Finally,the anthor discussed the reason that the restorer line Minghui82 of hybrid rice was widely utilized.
