高粱品种“晋辐57—1”是山西省汾阳农科所选育成功的。其选育过程是:1967年将配制的晋杂5号杂交种子(F_o),用γ射线1.8～2.6万伦琴的剂量照射。播种后第一代严重缺苗.有的小区甚至没苗,在缺苗最多的田块选择发育好的植株。在第二代时。表现出强烈分离,植株有高矮之分,粒色不同.壳色也不同等,出现了双亲没有的性状。“晋辐57—1”是从分离的植株中选出的一个品系,1968年拿到海南岛繁殖,1969年用它做父本与3197A 配制杂交种.定名“晋杂57—1”。
Sorghum variety “Jin spoke 57-1” Fenyang Agricultural Science Institute of Shanxi Province successful breeding. The breeding process is: 1967 will be prepared Jin hybrid No. 5 hybrid seeds (F_o), γ-ray dose of 1.8 to 26,000 Roentgen irradiation. After sowing the first generation of severe lack of seedlings. Some district even no seedlings, seedlings in the most lacking in the selection of well-developed plants. In the second generation. Showing a strong separation, the plants have the height of the points, different color, shell color is not the same, there is no parental traits. “Jin spoke 57-1” is a strain selected from the isolated plants, Hainan Island in 1968 to get breeding, in 1969 with its male parent and 3197A preparation of hybrids.
