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。
In this paper, the technologies of 0.4% ethyl methanesulfonate (EMS), 0.003, 0.005M sodium azide (NaN3) soaking, and γ-ray irradiation on live plants were introduced to broaden the variation of protein content and obtain high protein Effective Ways for Good Soybean Germplasm. To create some such as 90-3525, 91-3131, 91-3135 and other protein content of 46-48%, disease resistance, yield and other agricultural traits and good new lines and types.
