大豆品质育种的目标规定:蛋白质含量要达到50%,油分达到25%。要完成这个指标,首先要通过各种途径创造高蛋白或高油分含量的基因型。1976年我们用γ-射线处理杂种后代选育的“76—9029”、“76—9037”和“76—9106”等三个大豆高油分突变系,含油量已达23.91%～24.07%;通过化学诱变剂甲基磺酸乙酯(EMS)的处理,也获得了一批蛋白质含量超过45%的突变系。在这里,我们着重讨论中子和 EMS 对大豆蛋白质和油分含量的突变 Soybean breeding goal of quality requirements: protein content to reach 50%, oil reached 25%. To accomplish this goal, first of all, through a variety of ways to create high-protein or high oil content genotypes. In 1976, we used three γ-ray treatments of “76-9029”, “76-9037” and “76-9106” to breed high soybean mutant lines with oil content of 23.91% ~ 24.07% Chemical mutagen treatment of methyl ethyl methanesulfonate (EMS) also obtained a number of mutant lines with more than 45% protein content. Here, we focus on the neutron and EMS mutation of soy protein and oil content
