Genetic Analysis of Sepal Prickle Coverage in Eggplant
摘要
Abstract
To elucidate the genetic mechanism underlying the prickle coverage on eggplant sepals,six genetic populations(P1,P2,F1,F2,B1,B2)were constructed using the prickly line 24C01 and the prickle-free line 24C02 as parents.The number of prickles on sepals in the F1 population was investigated and exhibited a continuous and approximately normal distribution.Genetic analysis was per-formed using the major gene plus polygene mixed inheritance model.The optimal genetic model was identified as MX2-ADI-ADI,which consists of two additive-dominant-epistatic major genes plus additive-dominant-epistatic polygenes.Estimation of genetic pa-rameters indicated that the trait was primarily controlled by two major genes,with heritabilities of 89.70%,80.49%,and 74.64%in the F2,B1,and B2 populations,respectively.The expression of the trait was also influenced by environmental factors.In conclusion,this study provides a detailed analysis of the genetic pattern of calyx bristle traits,which holds significant implications for the directional improvement of eggplant varieties.关键词
