Abstract

The data of four traits: body weight after wool cut,woolcut,wool length and wool fineness were collected on one year old Chinese meat-type Merino(Xinjiang) ewes in Gongnaisi breeding sheep farm from April 1995 to April 2001.Estimations of heritability from half-sib's genetic covariance analysis for body weight after wool cut,woolcut,wool length and wool fineness are 0.519,0.416,0.466 and 0.325 respectively.And the phenotypic correlations and genetic correlations between these four traits are evaluated by correlation analysis.
