). We then analyzed the combining ability and heterosis of 6 reproductive traits in the F1, including male gonadosomatic index (_GSIelative fecundity (RF), fertilization rate (FR), and hatching rate (HRWe observed obvious differences among the reproductive traits between the different mating combinations. The highest were found in combinations in which the mother was “whole red with small black spots” (RS). The highest and RF were observed in combinations in which the mother was “whole red” (WR). Conversely, the values for these reproductive traits were low for combinations in which the mother was “whole white with big black spots” (RB). The phenotypic correlations among . We detected significant specific combining ability (SCA) for RF. Ten combinations were detected with predicted specific combining ability (SCA) and heterosis ( correlation between SCA and heterosis for M_GSI, F_GSI, AF, RF, and HR<0.01). Our results provided baseline data to guide breeding of complete set lines of Oujiang color common carp.
