花生栽培种类型较多,类型间的植株形态、生长习性、开花结实习性差异较大,这为花生新品种的选育提供了宝贵的材料。但是由花生自然群体进行简单选择或杂交育种,必须充分了解各类型品种主要性状的遗传变异规律。本研究估算了花生各类型品种主要经济性状的表型及遗传变异系数、遗传力、遗传进度、主要经济性状与单株生产力的相关,以期为直接选择及杂交育种提供依据。
There are many types of peanut cultivars, and plant types, growth habits and flowering and seed-setting habits are quite different among the types, which provides precious materials for the breeding of new peanut varieties. However, if peanut natural population is to be simply selected or crossbred, it is necessary to fully understand the laws of genetic variation of the major traits of various types of cultivars. This study estimated the phenotypic and genetic variation coefficient, heritability, genetic progress and major economic traits of main economic traits of various peanut varieties in order to provide the basis for direct selection and crossbreeding.
