| 摘 要： | 对菲律宾蛤仔中的斑马蛤、黑斑马、白斑马三品系进行混合选择,测量了各实验组的壳长,计算了不同品系斑马蛤的选择反应和现实遗传力。结果表明:3个品系的上选组壳长均大于对照组,说明单向上选是行之有效的遗传改良方法。在不同的生长发育阶段,斑马蛤品系的选择反应(R)和现实遗传力(2Rh)出现阶段性变化,从平均水平上看,R在幼虫期为0.688±0.184,稚贝期为0.605±0.214,养成期为0.670±0.120;2Rh在幼虫期为0.392±0.081,稚贝期为0.344±088,养成期为0.380±0.058。从一周年的生长情况来看,三个品系总的R为0.654±0.179,斑马蛤、黑斑马蛤和白斑马蛤品系的R分别为0.655±0.155、0.525±0.116、0.782±0.170;三个品系总的2Rh为0.373±0.070,斑马蛤、黑斑马蛤和白斑马蛤品系的2Rh分别为0.372±0.042、0.300±0.028、0.445±0.031。不同品系间R和2Rh次序为白斑马斑马蛤黑斑马,说明各斑马蛤品系的选择效果是不同的,品系间存在着一定程度的遗传差异。

| Abstract: | Three different zebra strains (Z: Zebra population; AbZ: Black zebra population; and WZ: white zebra population) of Manila clam Ruditapes philippinarumwere used to test growth trait by mass selection. The shell length of progenies were measured under microscope with vernier caliper. The response to selection and realized heritability were calculated. The results show that the shell length of all selective groups were significantly higher than that of the control (P<0.05) except for the AbZ. RS and RH of Manila clam varied in different development stages. The order of the response to selection and realized heritability among different zebra strains are as follow: WZ>Z>AbZ, which may be derived from the different genetic variation among three zebra clam strains. |
