亲本选配是谷子育种工作中的一个突出问题。谷子花器小,大量搞杂交组合有困难,如果仅根据一般原则从表型上选配亲本,效果不够理想。我们试用多元分析法定量测定亲本间遗传差异(以遗传距离度量),再根据遗传距离的大小对亲本进行分类,以便为杂交育种选配亲本提供依据。一、材料与方法 1.试验方法采用来自不同地区和具有不同性状特点的谷子品种49个:黑谷、代州黄、
Parental matching is a prominent issue in millet breeding. Millet flower small, a large number of engage in hybrid combinations difficult, if only according to the general principle of phenotypic matching parents, the effect is not ideal. We tried multivariate analysis to quantitatively determine the genetic differences between parents (measured by genetic distance), and then classified the parents according to the size of genetic distance in order to provide the basis for the selection of parents. I. Materials and Methods 1. The test method used 49 varieties of millet from different regions and with different traits: Black Valley, Dai Zhou Huang,
