【Abstract】 The purpose of this study was to find out the method of obtaining new genetic variation for increasing protein content of soybean seeds. The study indicated that soaking seeds with 0. 4 % of ethyl methanesulphonate at pH 7, 0. 003, 0. 005 M of of soldium azide at pH 3 and gamma rays chronic irradiation of 50Gy could induce gene mutations for high protein content in treated populations.Especially the progenies of treated F1 seeds might be used for selecting more mutants.Fot example,90- 3525,91 - 3131, 91- 3135 lines which have 46 - 48 percentage of protein are also disease resistant and with high yield potential.They may be used as high protein germplasm for subsequent breeding program.更多还原
