摘　　要：以黑穗醋栗半同胞家系子代测定林为研究对象,通过探讨果实性状的遗传变异规律综合分析了数量性状的遗传效应,并以此为基础材料,系统进行了优良家系的选择。结果表明,家系间果实性状存在一定的变异,其中,果径变异较小,果穗质量变异较大,单果质量变异最大,平均变异系数分别为2.75%、32.36%和40.41%。果径和果穗质量的遗传力较强,遗传增益中等,遗传分化较小,遗传力分别为0.995和0.811,遗传增益分别为1.28%和9.67%,综合考虑各种影响因素,确定RINI07为优良家系。The heredity effects of fruit characters from half-sib progeny were discussed,and the superior families were selected based on analysis of the genetic variation.The results showed that,there are certain differences on the berry characters among the families,and the coefficients of variance of the fruit diameter （2.75％） were smaller,but its each fruit cluster weight （32.36％） were larger and its average fruit weight （40.41％） were the largest.Meanwhile its berry character had strong heritability and medium genetic gain,and its genetic diversity was smaller.The heritability of the fruit diameter and the fruit cluster weight were 0.995 and 0.811,and the genetic gain were 1.28％ and 9.67％,respectively.So,taking influencing factors into consideration,RINI07 were determined to be the superior family.
