摘要
介绍了籼型长穗颈不育系K17eA的选育经过及其主要特性(如育性、柱头外露率、柱头活力、农艺性状、对920的敏感性);用K17eA作为母本,配制出了一批e型杂交水稻组合,其中2个组合已通过江西省农作物品种审定委员会审定。提出了K17eA的繁殖技术要点和制种技术要点。
The breeding process and the main characteristics （the fertility, stigna exsertion, stigma vigour, agronomic traits and the sensitivity to 920） of eui - type CMS line K17eA in indica rice were introduced in this paper. A series of e - type hybrid rice com- binations had been bred using K17eA as female parent, in which two had passed examination in Jiangxi province.
