本文分析比较了花生杂交和不同辐照方式结台杂交的早代后裔群体(4个群体,每个群体4个组合,共16个组合)8个性状的狭义遗传力和性状间的表型相关性。结果表明:3个辐照结合杂交的早代后裔群体与不加辐照的杂交早代后裔群体相比,饱果数、籽仁重等产量性状的狭义遗传力较高,并且增加了一些产量性状间的相关程度。3个不同辐照方式结合杂交的早代后簖群体之间比较,Υ辐照双亲和Υ辐照母本后进行杂交的两个早代后裔的数量性状遗传变异规律相似。
In this paper, the phenotypic correlations between the narrow heritability and traits of eight traits in early descendants (four populations, four combinations per population, 16 combinations) of peanut hybridization and heterotrophic hybridization were analyzed. Sex. The results showed that the narrow heritability of yield traits such as full fruit number and seed kernel weight were higher in the early progeny population with three combinations of irradiation and hybridization compared with the non-irradiated early hybrid generation population, and some yield Relevance of traits. The results showed that the genetic variation of quantitative traits in two early descendants crossed with γ and γ radiation was similar between the three groups of early generations with three different irradiation methods.
