摘要
通过彩鲫与红鲫杂交、回交以及不同体色彩鲫（杂交种）自交、杂交，对其子代的体色性状进行了统计学分析。彩鲫与红鲫的体色遗传说明彩色受显性基因控制，红色受隐性基因控制；不同体色彩鲫自交、杂交，其后代的体色分离特性为肉色显性，红色隐性，亲本体色在后代中可以积累增加；肉色、红色彩鲫与眼睛颜色、闪光鳞数具遗传相关性。
Through hybridazation and backcross of color crucian carp with red carp, as well as self-crossing and hybridazation of their color hybrids,the body color traits of their hybrids were analized statistically.The genetic regulation of body color for color and red crucian carp implies that the multicolors are controlled by recessive gene while the redness by dominant one. When hybrids of color crucian carp with different body colors hybridaze and self-cross,the flesh-color,in their hybrid body colors,shows recessiveness and red dominant,and the body colors of parents can be accumulated among their hybrids.There are genetic correlations between the eye color and flash-scale numbers of the flash-color and red crucian carps.
