Abstract: Fourteen variants of three sets of traits including body size traits,growth traits and carcass traits were measured and analyzed using canonical correlation analysis in Luxi cockfighting. The results showed that correlation coefficients were 0.682 to 0.767 between body size index (chest depth, chest width, shank length, bias length, chest bone length), 0.306 to 0.935 between growth traits(birth weight, 180 day weight, daily gain), and 0.945 to 0.986 between carcass performance (carcass weight, slaughter rate, semi-eviscerated weight, semi-eviscerated rate, and eviscerated weight, eviscerated rate) which were highly relevant. The results showed that the first canonical correlation were obtained between growth traits and body size traits(0.705), growth traits and carcass traits(0.560), body size traits and carcass traits (0.878). They accounted for 0.979,0.984 and 0.820 of total correlation,respectively.
