Abstract: Objective]This project mainly analyzes the differences and correlation relationship with wool traits among each strain.[Method]985 ewes of Chinese Merino Sheep(Xinjiang type)in Kunas breeding farm were taken as the research object,all the individual identification and shearing records were collected and the mean fiber diameter,fiber diameter coefficient of variance and crimp number were measureed in the laboratory room.SAS8.1 software was used to analyze the strains and birth season combined effects and groups effect in each wool trait in Chinese Merino Sheep (Xinjiang type)in order to identify the correlation between them.[Re-sult]The results showed that the strains and birth season combined effects have a extremely significant effect on staple length,crimp number,body size,greasy fleece weight,body weight B,body weight A and spinning count (P<0.01),and they also have a significant effect on fiber diameter coefficient of variance(P<0.05);Groups have a extremely significant effect on the mean fiber diameter,crimp number,oil,body weight A and spinning count (P<0.01)as well,and there were some correlations of each wool traits to different degrees.[Conclu-sion]Therefore,by means of comparing the difference between the wool traits among different strains and clear relationship among each trait,the results hope to provide a theoretical support for evaluating the wool quality and further selecting Chinese Merino Sheep (Xinjiang type).
