1.关于与无性繁殖结合的杂交育种命题类型例1小麦品种是纯合体,生产上用种子繁殖,现要选育矮杆(aa)、抗病(BB)的小麦新品种;马铃薯品种是杂合体(有一对基因杂合即可称为杂合体),生产上用块茎繁殖,现要选育黄肉(Yy)、抗病(Rr)的马铃薯新品种.请分别设计小麦间杂交育种程序以及马铃薯品种间杂交育种程序.要求用遗传图解表示并简要说明.(写出包括亲本在内前三代即可)切入分析对于新教材列举的自花传粉植物如小麦来说,
1. Propagation of Propagation Propositions Associated with Asexual Propagation Example 1 Wheat cultivars are homozygous and are propagated in seeds in seed production. New varieties of wheat (aa) and disease-resistant (BB) are to be bred. Potato cultivars are heterozygous (A hybrid with a pair of genes can be called hybrid), the production of tuber propagation, breeding of yellow meat (Yy), disease resistance (Rr) of the new potato varieties are to be.Please design wheat crossbred breeding program and Intercropping breeding programs between potato varieties requires the use of genetic illustrations and a brief description (including the parent, including the first three generations can be) into the analysis of new materials listed for self-pollinating plants such as wheat,
