摘　　要：成丰A是用福伊B与浙农8010的杂交F3单株与夏丰A测交后经多代连续回交转育而成的籼稻三系不育系,于2005年通过福建省科技成果鉴定,2015年获植物新品种权授权。成丰A表现优质、抗稻瘟病、大穗重粒、配合力强等特点。目前已利用成丰A配制出8个杂交水稻品种通过11次审定,其中国家审定3个。介绍了成丰A的选育过程、特征特性、配组表现及其繁殖技术要点。Chengfeng A is an indica CMS Line in rice developed by crossing the single plants selected from the F3 generation of Fuyi B/Zhenong 8010 to Xiafeng A followed by successive backcrossing over years. It was technically identified in Fujian Province in 2005 and authorized the new plant variety right in 2015. It has the characteristics of good grain quality, blast resistance, large panicle with heavy grains and high combining ability. By far, derived from Chengfeng A, eight hybrid rice varieties were released by eleven times, including three times of national registration. The breeding process of Chengfeng A, its characteristics and F1 hybrid performance and the key technical points of its multiplication were introduced in this paper.
