摘　　要：春江29A是中国水稻研究所选育的滇型晚粳稻不育系,已通过浙江省农作物品种审定委员会组织的不育系审定。该不育系育性稳定、分蘖能力较强、穗子较长、着粒密度较稀、异交结实率高。春江29A配合力强,利用春江29A与T7、CH15等籼粳中间型广亲和恢复系配组,杂种优势强,增产显著。Chunjiang 29 A is a Dian-type late japonica CMS line developed by China National Rice Research Institute. It was approved for release by Zhejiang Crop Variety Appraisal Committee in 2017. Chunjiang 29 A is characteristic of stable male sterility, strong tillering ability, low spikelet density with long panicles, high outcrossing rate and good combining ability. The combinations derived from Chunjiang 29 A and the indica-japonica intermediate type widecompatibility restorer lines such as T7 and CH15 showed strong heterosis with a significant yield increase.
