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. The progenitive technology and the seed production techniques of K17eA were put forward.
