| 摘 要： | 应用数量遗传学原理和全同胞组内相关法估计了40日龄大黄鱼的体长和体重遗传力,通过巢式平衡设计和人工授精技术,构建了5个半同胞家系和15个全同胞家系,利用SAS 9.0软件的一般线性模型(GLM)计算表型变量的方差组分,估计体长和体重性状的遗传力.结果表明:大黄鱼鱼种阶段体重和体长遗传力分别为0.29和0.31.t检验显示两个性状遗传力的估计值均不显著,且雄性遗传方差组分大于雌性遗传方差组分,说明雄性遗传方差组分存在非加性效应或受环境影响较大. |

| Abstract: | In the study,the heritability of body length and body weight in Larimichthys crocea was estimated by means of intra group correlation of full-sibs at 40 days after hatching.Five sires and fifteen dams were mated by an artificial insemination technique and nesting balance design.Causal components of phenotypic variance were calculated with the GLM(General Linear Model)procedure of SAS 9.0 software.The results showed the heritabilities of body weight and body length were 0.29,0.31 respectively.The heritabilit... |
