为解决杂交高梁的抗蚜虫问题,我们从1972年开始,从引入的品质较好的国外杂交种(NK_(222)、NK_(255)、NK_(265)等)中分离高梁新品种,并在分离的早期世代用优质的中国高梁品种做父本进行杂交,现已分离出几十个优质品系,其中最好的品系表现了籽粒透亮、优质高产、单宁含量极低、基本不着壳等优点,而且有3个系(优抗75-1、75-2、41-1)表现了高度抗蚜虫危害,目前已在生产上推广种植,受到群众欢迎。
In order to solve the problem of aphid resistance of hybrid sorghum, we have isolated new varieties of sorghum from introduced exotic hybrids (NK_ (222), NK_ (255), NK_ (265), etc.) The early isolated generations were crossed with high quality Chinese sorghum breeds as paternal parents, and dozens of high quality strains have been isolated. The best of them shows the advantages of translucent seeds, high quality and high yield, very low tannin content, essentially no shell , And 3 lines (Youkang 75-1, 75-2 and 41-1) showed high resistance to aphids. Currently, they have been popularized in production and are welcomed by the masses.
