育种目标确定以后,亲本选择就成为育种成败的关键。亲本选择的原则,除要注意选择地理远缘或生态远缘,优点多、缺点少而且优缺点可以互补的亲本外,还要注意亲本的血缘关系。通过分析现有品种和亲本材料的系谱,有助于了解各个品种的演变历史、血缘关系以及主要经济性状的遗传规律或动态,同时,还可以了解亲本材料的配合力。本文是针对由我省选育并得到大面积推广的几个小麦品种,进行其主要性状表现和系谱的分析,以提供亲本选择方面的经验。 After the breeding target is confirmed, the choice of the parents becomes the key to the success or failure of breeding. In addition to pay attention to the selection of geographical or eco-distant edge, the advantages of the parent, the advantages and disadvantages of fewer and fewer advantages and disadvantages can complement each other, but also pay attention to the blood relationship of the parents. By analyzing the pedigree of the existing cultivars and parental materials, it is helpful to understand the evolutionary history, kinship and the genetic laws or dynamics of the major economic traits, as well as to understand the combining ability of parental materials. This article is aimed at the wheat varieties bred in our province and popularized in large area, and analyzed their main traits and pedigree to provide their parents with experience in selection.
