本试验应用x-射线和γ-射线处理6个大豆品种和4个杂种后代。分析了上述诱变因素对大豆M_1和M_2的诱变效应。γ-射线对M_1的存活率、植株的生长和育性都有明显的影响。x-射线和γ-射线处理的后代(M_2)在熟期、抗病性和形态特征等都产生了很大变异。这些突变体是培育不同熟期、抗病和优质的新品种的重要种质材料。通过改良系谱—混合选择法已选育出6个抗病、优质和丰产的大豆新品种。1982年诱变4号、10号、16号和30号已推广约40万亩。
In this experiment, 6 soybean varieties and 4 hybrid progeny were treated with x-ray and γ-ray. The mutagenic effects of mutagens on soybean M_1 and M_2 were analyzed. γ-ray has a significant impact on the survival rate of M_1, plant growth and fertility. The offspring of x-ray and γ-ray treatment (M_2) produced great variation in maturity, disease resistance and morphological characteristics. These mutants are important germplasm materials for breeding new varieties of different maturity, disease resistance and quality. Six resistant, high quality and high yield new varieties of soybean have been bred by the improved pedigree-hybrid selection method. Mutagenization 1982, No. 4, No. 10, No. 16 and No. 30 have been promoted about 400,000 mu.
