我们学习遗传定律时在讲育种工作的应用时,常常遇到这样的例子:现有小麦高秆抗病、矮秆易染病的两纯合品种,需要获得优良品种,请设计快速育种的方案。我们在处理此问题时,首先要进行杂交,将两优良性状组合到一起,最后获得纯合子。但是实际生产中往往用的是杂交的杂种种植,在生物人教版选修全一册也 When we talk about the application of genetics, we often encounter such an example when we talk about the application of breeding laws. For two homozygous varieties with high stalk resistance and dwarf susceptibility to wheat, you need to obtain good varieties. Design a program for rapid breeding. When we deal with this issue, we must first carry out hybridization, the two excellent traits combined together, and finally get homozygotes. However, the actual production is often used hybrid hybrids, bio-PEP elective whole book also
