摘要
本文阐述了０．４％甲烷磺酸乙酯（ＥＭＳ），０．００３、０．００５Ｍ叠氮化钠（ＮａＮ３）浸种，γ射线慢照射活体植株等技术，是拓宽蛋白质含量变异，获得高蛋白大豆优良种质的有效途径。创造出一些如９０—３５２５、９１—３１３１、９１—３１３５等蛋白质含量４６—４８％，抗病性，产量等农业性状兼优的新品系和类型。
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.
