我所一九七○年开展 Co~(60)-γ射线辐射育种的研究,一九七三年在辐射引变的同时利用稳定突变系与冬、春小麦品种及突变类型间进行杂交。几年来,选育出了“辐_1”、“辐_2”两个品系已在我区推广,“辐系_3”进入了区试和多点示范。实践证明,辐射引变是选育新品种的有效途径之一。经过几年的工作我们有以下初步体会。一、原始材料的选择是决定性的前提

In 1970, I conducted the research on the radiation of Co ~ (60) -γ-ray radiation. In 1973, I used the stable mutation line to make the hybridization with the winter and spring wheat varieties and the mutation types. In recent years, the breeding of the “spoke _1”, “spoke _2” two lines have been promoted in our district, “spoke _3” into the district test and multi-point demonstration. Practice has proved that radiation induction is one of the effective ways to breed new varieties. After several years of work we have the following initial experience. First, the choice of raw materials is the decisive premise
