| 摘 要： | 收集合浦珠母贝(Pinctada martensii)F4选育组和对照组不同月龄生长数据,对壳长、壳高、壳宽和体质量进行相关和回归分析。结果显示,各月龄选育组和对照组生长性状间相关系数均达到极显著水平(P0.01),相关系数范围分别为0.47~0.88和0.44~0.92。除选育组6月龄壳宽与其他性状间相关系数大于对照组相应数值外,选育组生长性状间相关系数均小于对照组。各月龄选育组和对照组估算体质量的多元回归均达到显著水平(P0.05),方程判定系数(R2)范围分别为0.625~0.848和0.745~0.902,选育组方程判定系数均小于对照组。该研究结果为合浦珠母贝选择育种工作中确定重要目标性状提供了理论指导。

| Abstract: | In this study, growth data at different cultured months of forth generation selective group and control group of pearl oyster Pinctada fucata were measured, and the correlation and regression analysis for shell length, shell height, shell width and weigh were conducted. The results showed that correlation coefficients among growth traits of selective group and control group at three cultured months were extremely significant (P<0.01), and were 0.47~0.88 and 0.44~0.92 respectively. Except correlation coefficients between shell width and others traits of selective group at six cultured month, correlation coefficients among growth traits of selective group were smaller than corresponding values of control group. The multiple regression equations estimated body weight of selective group and control group were significant (P <0.05), and coefficients of determination (R2) were 0.625~0.848 and 0.745~0.902 respectively. Coefficients of determination of selective group were all smaller than corresponding values of control group. The results of this paper provides theoretical guidance for determining the important target traits in selective breeding of Pinctada fucata. |
