| 摘 要： | 以合浦珠母贝(Pinctada fucata)4种壳色选育群体为亲贝,采用人工授精技术对同一壳色亲本进行雌雄单个配对,获得了15个全同胞家系。测量5、15、25和40日龄时的壳长和壳高,利用方差分析比较不同壳色品系的生长差异;利用非求导约束最大似然法(DF-REML)对合浦珠母贝各日龄的壳长和壳高性状进行遗传参数的估计。结果表明,4种壳色系的壳长和壳高均存在显著差异(P<0.05);5～40日龄幼体壳长遗传力估计值为0.12～0.22,壳高遗传力估计值为0.17～0.23;合浦珠母贝幼体不同生长时期壳长和壳高的遗传相关和表型相关均为正相关,相关系数分别为0.825～0.989和0.832～0.965,表明以壳高或壳长为参数进行选育时,均可达到改良生长性状的效果。

| Abstract: | Using artificial fertilization of male and female with same shell color,fifteen full sib-families were obtained from four different shell colors parent Pinctada fucata.The shell length and shell height of 5,15,25 and 40 days P.fucata were measured.The growth differences among the four shell color lines were evaluated using the analysis of variance.Genetic parameters of shell length and shell height of P.fucata were estimated using DF-REML.Significant differences of shell length and shell height were found i... |
