摘要

对给定表型的遗传力的估计将为潜在的育种计划提供基本信息。黄河鲤鱼是我国最珍贵的鲤鱼品种之一,为满足市场需求,选用生长快、体细的品种。在本研究中,基于来自58个半同胞和全同胞黄河鲤鱼家族的750个后代的分子亲本分配,估计了体型(体长、BL和身高、BH)和体重(BW)的遗传力。使用8个高度多态性的微卫星构建分子家系,平均观察杂合度(Ho)、预期杂合性(He)和多态性信息含量(PIC)分别为0.841、0.792和0.763。所有750个后代都以100%的准确率成功地分配到单亲配对中。使用线性混合模型,BL、BH和BW的遗传力分别估计为0.268、0.338和0.340。这三个性状之间的高表型(0.831-0.927)和遗传(0.952-0.987)相关性表明,对BW的选择也可能在很大程度上影响体型,反之亦然。本研究所揭示的中等遗传力和高遗传校正有力地表明,在黄河鲤鱼育种计划中,生长速度和体型的遗传改良具有巨大的潜力。

Estimation of the Heritabilities for Body Shape and Body Weight in Yellow River Carp (Cyprinus carpio haematopterus) Based on a Molecular Pedigree
Estimation of the heritability for a given phenotype would provide basic information for potential breeding programs. As one of the most precious common carp strains, Yellow River carp was subject to selection for fast growth and a slender body to meet market demands. In the present study, heritabilities for body shape (body length, BL and body height, BH) and body weight (BW) were estimated based on a molecular parentage assignment for 750 progenies from 58 half-sib and full-sib Yellow River carp families. Eight highly polymorphic microsatellites were used for the construction of the molecular pedigree, and the average observed heterozygosity (Ho), expected heterozygosity (He), and the polymorphism information content (PIC) were 0.841, 0.792, and 0.763, respectively. All 750 progenies were successfully assigned to single parental pairs with 100% accuracy. Using the linear mixed model, the heritabilities were estimated to be 0.268, 0.338, and 0.340 for BL, BH, and BW, respectively. High phenotypic (0.831–0.927) and genetic (0.952–0.987) correlations among these three traits suggested that selection for BW could also largely affect the body shape and vice versa. Moderate heritabilities and high genetic corrections revealed by this study strongly indicate substantial potentials for genetic improvement of both growth rate and body formation in Yellow River carp breeding programs.
