Those were dominant genetic correlation between CRE,CRL and HRL and similar negatively dominant genetic correlation between CRE,HRL and GL. In addition,both of their absolute correlation coefficient values were larger than that between CRE and CRL.

• CRL、HRL与CRE之间主要表现为显性遗传相关,HRL、GL与CRE的显性遗传负相关性相近,显性相关系数均大于CRL;
