| 摘 要： | 利用7个凡纳滨对虾(Litopenaeus vannamei)引进群体,通过双列杂交和巢式交配设计构建家系,建立育种基础群体,估计体重、存活性状的遗传参数和基因型与环境互作效应(genotype by environment interactions,G×E)。结果表明,凡纳滨对虾基础群体体重和存活性状的遗传力估计值范围分别在(0.19±0.09)—(0.43±0.09),(0.27±0.04)—(0.45±0.06),均属于中高遗传力水平,并且统计检验显著(P<0.05)。Z-score检验表明,体重和存活性状遗传力估计值在河北黄骅(HBHH)和青岛鳌山(QBAS)两个测试场间差异均不显著。体重和存活性状的表型和遗传相关系数分别为0.007和0.008,表现为低度线性负相关。对于体重和存活性状,HBHH和QBAS场间的遗传相关分别为0.83±0.04和0.40±0.11。体重性状的G×E效应不显著(K<0.5),但存活性状存在显著的G×E效应(K>0.5)。上述结果显示,凡纳滨对虾基础群体体重和存活性状的遗传变异丰富,多代选择可获得较大的遗传进展。

| Abstract: | Genetic parameters and genotype by environment interaction (G×E) were obtained for body weight and survival of Pacific white shrimp Litopenaeus vannamei using full-sib and half-sib families from cultured brood females collected from seven introduced populations. The heritability estimates for body weight and survival in the base population all ranged from moderate to high (0.19±0.09) to (0.43±0.09), (0.27±0.04) to (0.45±0.06)] and were significantly different from zero (P<0.05). The heritabilities estimated between two farm units (HBHH and QDAS) at different locations (Huanghua city and Qingdao city) were not significantly different from each other (P>0.05) for body weight and survival using Z-score test. There was a low phenotypic and genetic correlation between body weight and survival (?0.007 and ?0.008).The genetic correlations between HBHH and QDAS farms were 0.83±0.04 for body weight, and 0.40±0.11 for survival. These correlations suggest that a low G×E effect for body weight (K<0.5), but a high G×E effect for survival (K>0.5). The results show that there is quite substantial additive genetic variance for body weight and survival in Pacific white shrimp that can be exploited through selective breeding. |
