Heritability of larval shell length for Zhongke No. 2 bay scallop (Argopecten irradians)
摘要
Abstract
In this study, we estimated the heritability of the shell length of the Zhongke No. 2 bay scallop, Argopecten irradians,by performing an intra-group correlation of full-sibs at 1 day and 6 days after hatching. Each sire was mated with three dams in a balanced nested design, and 7 half-sib groups and 21 full-sib families were produced in total. We calculated the causal components of the phenotypic variance using the general linear model (GLM) procedure and SAS 9.0 software. The results showed that the heritabilities of shell length of 1 day and 6 days were 0.51 and 0.58, respectively. The heritabilities of both these stages failed to reach their prominent level by t checkout. Maternal genetic variance was significantly greater than paternal genetic variance in 6 days, which indicates the existence of greater maternal effect. The estimated heritability indicated great additive variation in growth at the larval stage. This additive variation suggests a reasonable potential for the improvement of larval growth of the Zhongke No. 2 bay scallop for further selective breeding.关键词
