摘要: 以野败不育系作鉴别,从栽培稻(野败恢复系)中发掘获得10个含有新不育胞质的品种。利用其中的印尼水田谷6号不育胞质,先后育成了印水型系列不育系Ⅱ-32A、优1A、中9A。印水型不育系有配合力高、稻米品质好、开花习性好、制种产量高、成本低等特点。至2005年,利用印水型不育系配制的印水型杂交稻组合在国家和各省市审定的已达203个,印水型杂交稻组合在全国已累计推广2.8×107 ha以上,年应用面积达3.5×106 ha以上,占我国杂交水稻种植总面积的1/4,成为我国第二大不育胞质类型杂交水稻。

Abstract: Ten new cytoplasmic male sterile (CMS) lines were discovered through hybridization from cultivated varieties (WA-type restorer) in rice (Oryza sativa L.). A series of new CMS lines with Indonesia 6 (ID) cytoplasm such as II-32A, You 1A, and Zhong 9A were developed, which were characterized by good combining ability, good grain quality, good flowering habits, high seed production yield potential, and lower production cost. Up to 2005, 203 new hybrid rice varieties produced from Indonesia 6-type CMS lines were officially released by provincial and national governments. The accumulated planting areas of these ID-type hybrid rice varieties were 28.0 million hectares in the whole country, and the annual planting area was about 3.5 million hectares, occupying 25 per cent of the total hybrid rice planting area in China. It becomes the second biggest CMS utilized in China. It has won the National S&T award.
