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.
