摘　　要：本文以维多利亚为父本、红地球为母本有性常规杂交获得的F1代杂交后代主要果实性状为研究对象,调查分析了杂交后代主要果实性状遗传倾向。结果表明:果穗主要测量性状平均变异系数为33.34%,平均遗传传递力为89.6%,果粒主要观测性状平均变异系数为17.6%,平均遗传传递力为101.72%。5个主要测量性状的遗传传递力大小顺序依次为果穗重 】果穗长 】穗梗长 】果穗大小 】果穗宽。In this paper, the genetic tendency of the main fruit characters of F1 hybrids was investigated by using Victoria as the male parent and Red Earth as the female parent. The results showed that the average coefficient of variation (CV) of the main characters measured in the panicle was 33.34%, the average heritability was 89.6%, the average CV of the main characters measured in the grain was 17.6%, and the average heritability was 101.72%. The order of heritability of the five main characters measured was ear weight >ear length >ear stem length >ear size >ear width.
