摘　　要：通过对新选三系雄性不育系黔丰 A的各个性状分析 ,结果显示 :该不育系的花粉败育率为99.9%左右 ,株高 6 0 cm左右 ,分蘖力强 ,千粒重 2 8g左右 ;柱头外露率为 85 .1% ,高于各对照不育系。其组配的杂交 F1的结实率 (% )和单株产量都分别比对照种汕优 6 3高。The main characters of new type CMS line, Qianfeng 11A(abbreviated: QF11A) was analyzed . The results showed: pollen sterility of this CMS line was 99.9%, plant high was 60cm, 1000 grain weight is 28g;Pillar out rate of it was 85.1%, higher than that of the check line. The hybrid combined with 11A showed higher seed setting rate and yield per plant than that of using Shanyou 63(CK).
