在高粱的分类学里,高粱野生近缘种遗传资源比较丰富,如苏丹草、突尼斯草、约翰逊草、丰裕高粱、拟高粱等。在这些野生近缘种资源中,蕴含有许多可以利用的基因,如抗病、虫,抗逆境等抗性基因,在高粱品种遗传改良中,有的可以直接利用,有的可以间接利用。例如,利用苏丹草与栽培高粱杂交,其杂交种可以作为饲草高粱在生产上推广利用,我国近年选育的皖草2号、晋草1号、辽草1号等均是野生近缘高粱种利用的实例。而且,随着科学技术的进步,高粱野生近缘种将会得到广泛的利用。
Sorghum taxonomy, sorghum wild relatives of genetic resources rich, such as Sudan grass, Tunisian grass, Johnson grass, abundance sorghum, sorghum and so on. Among these wild relatives, there are many genes that can be used, such as disease resistance, insect resistance and stress tolerance. Some of them can be directly used in genetic improvement of sorghum and some can be indirectly used. For example, the use of Sudan grass and cultivated sorghum hybrids, the hybrids can be used as forage sorghum in the production of promotion and utilization in China in recent years breeding Anhui grass 2, Jincao 1, Liao Cao 1 are the wild relatives of sorghum Examples of utilization. Moreover, with the progress of science and technology, sorghum wild relatives will be widely used.
