本文估算了花生11个性状的遗传进度和选择指数等遗传参数。结果表明,性状间遗传力存在较大差异,应据此掌握各世代不同性状的选择标准。对单株产量的直接选择很重要,单株结果数是相关选择的关键性状,选择饱果数多、侧枝长的材料对单株产量也有一定的改良效果,选择时应予以重视,而百果重、百仁重不是产量的限制因素。花生育种应用选择指数方法进行综合选择比对单株产量单一性状直接选择的效率提高23.22％,应用前景广泛。
In this paper, genetic parameters such as genetic progress and selection index of 11 traits in peanut were estimated. The results showed that there was a big difference in heritability between traits, and the selection criteria of different traits should be grasped according to this. The direct selection of the yield per plant is very important. The number of single plant results is the key trait of the relevant selection. Choosing the full number of fruit, the material with long branches has a certain improvement effect on the yield per plant, and the selection should pay attention to it. Heavy, heavy weight is not a limiting factor in production. The selection of peanut breeding selection index method for comprehensive selection of single traits per plant yield increased by 23.22%, the application prospects of a wide range of applications.
