摘　　要：乐丰A是以金23B//福伊B/建伊B选育保持系,再与福伊A测交并连续回交转育而成的水稻三系不育系,于2004年通过福建省科技成果鉴定,2008年获植物新品种权。乐丰A具有农艺性状好、配合力高、异交特性好、米质优、稻瘟病抗性强等特点,目前已利用乐丰A配制出12个杂交水稻品种通过省级以上审定。介绍了乐丰A的选育过程、特征特性及配组利用情况。Lefeng A, derived from the cross of Fuyi A///（ Jin 23B ff （Fuyi B/Jianyi B）F2 ）F3 and its successive backcrosses, is a new CMS line in rice. It was technically identified in Fujian Province in 2004 and was granted a new plant variety right in 2008. It is characteristic of high combining ability, good outcrossing habits, fine grain quality and strong blast resistance. Up to now, there have been 12 hybrid combinations derived from Lefeng A re- leased by provincial or national crop variety appraisal committees. The breeding process, characteristics and appli- cation of Lefeng A were introduced in detail in this paper.
