摘　　要：利用60Coγ射线对菏豆12进行辐照处理,于M4、M5连续两代进行田间观察和室内鉴定,对其株高、结荚高度、茎粗、有效分枝、主茎节数、单株荚数、单株粒数、百粒重、单株粒重等主要农艺性状进行简单相关性分析,探讨诱变后代的遗传变异机制,并从诱变后代中筛选与产量有关的变异。结果表明,诱变后代大量植株的叶形、花色、脐色、生育期、茸毛颜色等表型性状发生了不同程度的分离与变异;对菏豆12及其诱变后代群体的主要产量相关性状进行分析,筛选出与单株产量相关性较大的变异,同时通过遗传距离分析确定了变异的遗传稳定性,为诱变后代的选择提供了理论指导。The soybean variety Hedou 12 was irradiated with ^60Co γ- ray and the field observation and indoor identification of M4 and M5progenies were conducted. The main agronomic characters such as plant height,pot- setting height,stem diameter,effective branch,node number of main stem,pods per plant,grain number per plant,100- grain weight and grain weight per plant were made simple correlation analysis to discuss the genetic variation mechanism of mutagenesis progenies and screen yield- related variations. The results showed that most leaf shape,flower color,hilum color,growth period and pubescence color of mutagenesis progenies had different degrees of separation and variation. The main yield- related traits of Hedou 12 and its mutagenesis progenies were analyzed,and the variation which had large correlation with yield per plant was screened out. At the same time,the genetic stability of variation was determined by genetic distance analysis,which provided theoretical guidance for selection of mutagenesis progenies.
