摘　　要：启源A是以253B/繁源B育成的保持系与全丰A测交、回交转育而成的水稻三系不育系,于2020年通过福建省品种审定。启源A表现不育性稳定,异交率高,米质优,配合力强,耐高温性好,配制的杂交稻组合熟期早,目前已配制出2个杂交水稻组合通过省级审定,并有多个组合参加各级试验。Qiyuan A is a CMS Line in rice developed by crossing the maintainer line selected from the filial generation of 253B/Fanyuan B to Quanfeng A followed by successive backcrossing for years. In 2020, it was registered by Fujian Crop Variety Appraisal Committee. It shows stable male sterility, high outcrossing rate, good grain quality, high combining ability, good heat tolerance and early maturity in hybrids. Two hybrid combinations derived from Qiyuan A have been registered and released for commercial production, and several other hybrid combinations have been tested in the regional trials at all levels.
