摘 要 ：利用太谷核显性核不育基因，开展小麦株粒重、株穗数和株高三个性状的轮回选择，研究群体改良的效果。经四轮选择看出：（1）株粒重增加8.25g，平均每轮增加2.06g；株穗数增加5.25个，平均每轮增加1.31个；株高降低8.82cm，平均每轮降低2.21cm。三个性状态参数的论间差异显著。（2）随轮选次数的递增，群体平均值朝着附合育种

Abstract:The dominant male sterile gene Tal was used for recurrent selection on grain weight/plant, ears/plant, and plant height in wheat to investigate the effects of population improvement. Four cycles of selection indicated: 1. From Co to C4, 8.25g were achieved for grain weight/plant (2.06g for per cycle
