摘要： A novel method was produced to explore the catch-up like growth from diallel cross-breeding due to its similarity with high growth speed in the later period for common carp Cyprinus carpio L cross-breeding. A compensatory index matrix for 3x3, full diallel cross combinations used for selection was built to investigate compensatory like growth of each combination. Yes/No(Y/N) effect was determined for specific combination dyads, which there were significant differences in body weight at tagging, but no difference in body weight at harvesting. Among the 36 dyads, 7 had an YN response (19.4%). When the YN effect had a fixed accumulated value, the value reflected its compensatory like growth degree, i.e., no catch-up like growth in one group means no YN effect in one group can be detected. Heilongjiang carp male x Jian carp female (Yj) combination had the highest catch-up like growth degree and the Heilongjiang carp male x Heilongjiang carp female (Yy) combination had no compensatory like growth. Reference standard was set as arithmetic progression in 5% each step for the whole group (e.g. 5%, 10%, 15%, etc.) Compared the harvesting weight and weight gain, significant differences were found between non-compensatory like growth and compensatory like growth group on all levels except the 25% level. Particularly, the 35% level had the biggest compensatory like growth. Body shape changed during the compensatory like growth process. This study shows that compensatory like growth of body weight during the cross-breeding can be detected and quantified.
