Abstract:
4 Yellow Catfish populations collected from Chaohu,Gehu,Hongzehu and Taihu were used to be hybrid parents and 63 hybrid combinations were constructed.When the fish grew to 6 month old,50 individuals were randomly selected from each group to measure in body weight and body length.The results showed that the maximum length was 2.5 times as that of the minimum.As well as 15.5 times in body weight.There was a significant difference in the body weight and body length between intra-family and inter-family groups.The correlation analysis on the source of parents and offspring growth performance indicated that Chaohu Yellow Catfish population were suitable to be female parent and Gehu populations were suitable to be male parent.The relationship between the weight and length was found to follow a power function,W=0.012L2.878g/cm2.87(R2=0.970),which indicated that F1 generation that contained a number of growth performance high progeny were in rapid growth.
