高异交率、抗稻瘟病水稻三系不育系全丰A的选育与利用

全丰A 是福建省农业科学院水稻研究所以福伊B为母本、谷丰A的低世代保持系材料为父本进行杂交配组选育的保持系， 再与福伊A转育而成的野败籼型三系不育系。于2004年通过福建省科技成果鉴定， 2008年获得植物新品种权。多年研究结果表明， 全丰A表现配合力强、 异交率高、 抗稻瘟病、 适应性广等特点。目前已利用全丰A配制出10个杂交水稻组合通过22次新品种审（认）定。笔者概述了全丰A的选育过程、 特征特性及高产繁殖技术。

Breeding and Utilization of the CMS Line Quanfeng A with Fine Blast Resistance in Rice

Quanfeng A is a CMS Line in rice bred by the Rice Research Institute, Fujian Academy of Agricultural Sciences, by crossing the maintainer lines selected from the hybrid between Fuyi B and Gufeng B with Fuyi A through successive backcrossing for years. It was technically tested in Fujian Province in 2004 and acquired the protection of new varieties of plants in 2008. It was proved by many years of its application on production that the CMS Line had the characteristics of strong combining ability, wide adaptability and high stigma exsertion and outcrossing rate, good resistance to rice blast. By far, derived from Quanfeng A, Ten hybrid rice combinations were officially approved twenty-two times. The process of breeding Quanfeng A, its characteristics and reproduction of seeds were referred in this paper.
