摘要： 本文研究了大豆产量轮回选择下主要农艺性状平均数及遗传方差——协方差的响应。试验数据取自早、中、晚3组的亲本和3个周期在2年2地点的随机区组试验。3组资料合并分析。产量、成熟期、倒伏程度、株高及百粒重五维空间中,产量轮回选择的第一、二周期优系亚群体离亲本的距离显著增加,而初始周期选择便显著改变产量本身,对产量

Abstract: This study is a further analysis of Sumarno and Fehr's data (1982)to evaluate the responses of means and variance--covariances of agronomiccharacters to recurrent selection for yield. Data were from three maturitysets, each having 13 or 14 parent strains and 10 super selections of eachof three succe
