Abstract：The soybean variety Hedou 12 was irradiated with 60 Co γ-ray and the field observation and indoor identification of M 4 and M5 progenies 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 re-sults showed that most leaf shape , flower color , hilum color , growth period and pubescence color of mutagene-sis 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 .
