摘要
本文报告了长毛对虾(Penaeus penicillatus)体长和体重的一些遗传参数:在体长为10.2092±0.0321(cm),体重为14.0696±0.1273(g)时,雌雄之间的大小有显著差异,雌体大于雄体。此时,体长与体重之间有极显著的直线相关(r=0.7914,P<0.01)。体重对体长的回归直线为Y=3.1414x-18.0016,其中雌性为Y=3.2803x-19.1357,雄性为y=2.5314x-12.1378。体长对体重的回归直线为x=0.1994Y+7.4037,其中雌性为x:0.1952y+7.4436,雄性为x=0.2219y+7.1233。长毛对虾体长的全同胞同类相关系数为0.3242,体重的全同胞同类相关系数为0.0805。
Some genetic parameters of the body length and body weight of Penaeus penicillatus are reported in this paper: There is a significnat dif ference in the size between female and male,when the length is 10.2092 ±0.0321 (cm) and the weight is 14.0696±0.1273 (g) , i.e. the female is larger than the male in general. There is significant straight linear cor relation between body lenght and body weight (r=0.7914 p<0.01). The regressive equations of the straight line of body weight upon body length is of the form: y=3.1414x-18.0016. The regressive linear epuations of body length upon body weight is of the following form: x=0.1994y+ 7.4037. The resemblance among full sib families in the body length is 0.3242, and in the body weight is 0.0805.
