| 摘 要： | 对不同地理群体的3龄菲律宾蛤仔(Pp莆田群体、Dp大连群体、Tp东京群体)进行了混合选择。测量了各实验组的壳长,计算了不同地理群体菲律宾蛤仔的选择反应和现实遗传力。结果表明,3个地群体菲律宾蛤仔子代的上选组壳长显著大于对照组(P<0.05)。在不同生长发育阶段,菲律宾蛤仔的选择反应(R)和现实遗传力(hR2)随着日龄的增大而减小,即R幼虫培育期0.804±0.084>稚贝期0.705±0.039>养成期0.671±0.024;hR2幼虫期0.458±0.051>稚贝期0.402±0.025>养成期0.382±0.013。从总体水平上分析,菲律宾蛤仔R为0.726±0.1074,莆田群体、大连群体、东京群体的R分别为0.758±0.101、0.690±0.049、0.732±0.059;hR2为0.414±0.044,莆田群体、大连群体、东京群体的hR2分别为0.432±0.058、0.393±0.028、0.417±0.033。地理群体间的R和hR2次序为莆田群体>东京群体>大连群体,且彼此间无显著差异。 |

| Abstract: | Three geographical populations ( Pp: Putain population; Dp: Dalian population; Tp: Tokyo population) of Manila clam Ruditapes philippinarum of 3-years old were used to test mass selection on growth in July 2006. Shell length of individual was measured by microscope and vernier caliper,moreover,responses to selection and realized heritability were calculated by the methods of Zheng,et al. (2004,2006) among three geographical populations of Manila clam. The results showed that the shell length of selection gr... |
| Keywords: | Ruditapes philippinarum geographical population response to selection realized heritability |
