Genetic Analysis of Shelling Percentage in RIL Population of Peanut
The shelling percentage is one of the yield traits of peanuts and is an important impact factor in kernel yield.This study used a recombinant inbred line(RIL)population constructed from Hu-ayu44XDF12 as the experimental material.The shelling percentage was used as the phenotypic data,and a genetic characteristic analysis of the shelling percentage was conducted under three different environmental years using a major gene plus polygene mixed genetic model.The results indicated that the optimal genetic model for shelling percentage in all three environmental years was the 4MG-AI model,which involves four pairs of additive-epistatic major genes.The major gene heritability in the three environmental years was 91.93％,90.60％and 96.85％,respectively.The results of this study provided an important theo-retical basis for understanding the genetic mechanisms of the shelling percentage.
