原始材料始终是农作物肓种的一个中心问题。近年来,它的作用显得非常之大。这是因为育种方面还存在着许多复杂的课题需要解决,不管是要提高产量,还是要提高抗性和产品质量。随着育种的发展,创造原始材料的方法也日趋完善。从作为选择源的地方推广品种到解决遗传多样性的办法,如杂交、诱变,单倍体,杂种优势以及其他一些方法,都是获得原始材料的一些重要途径。借助这些途径得到的原始材料,是培育优良的超亲的综合性状较好的品种的基础。
The raw materials have always been a central issue for crop species. In recent years, its role has become very large. This is because there are still many complex issues that need to be solved in breeding, whether to increase production or to increase resistance and product quality. With the development of breeding, the methods of creating raw materials are also getting better and better. From promoting the variety as a source of selection to addressing genetic diversity such as crosses, mutagens, haploids, heterosis, and other methods are some of the key ways to get raw materials. The raw materials obtained by these means are the basis for cultivating better super-parents with better comprehensive characters.
