This study estimated heritability of 13 characters in third generation of Putian Black Ducks using method of sib correlation analysis.It also estimated correlation among major characters.The result showed:Heritablities of egg number in Various periods was high,egg weight was low.Body weight and first laying age had middlle heritability.Egg number and egg weight in various periods were positively and highly correlated with hereditary and middlingly correlated with phenotype.Egg number at 300 days and first laying ages were negatively correlated with hereditary and phenotype.Egg weight ay 300 days and body weight in the same period were positively correlated with hereditary and middlingly correlated with phenotype.
