Genetic studies of south australian merino sheep 4. genetic phenotypic and environmental correlations between various wool and body traits



Genetic studies of south australian merino sheep 4. genetic phenotypic and environmental correlations between various wool and body traits



Australian Journal of Agricultural Research 33(2): 363-374



Genetic, phenotypic and environmental correlations were estimated between 23 quantitative and qualitative wool and body traits of South Australian Merino sheep. Clean fleece weight was significantly correlated genetically with greasy fleece weight (0.62), yield (0.47), staple length (0.41), crimps per inch (-0.34), secondary/primary follicle ratio (0.37) and skin thickness (0.39). No significant half-sib genetic correlation was found between clean fleece weight and fiber diameter, and the dam-offspring correlation was quite low, although significant (0.16, P < 0.05). Selection for clean fleece weight should not lead to any great increase in fiber diameter. Skin thickness is discussed as a possible early indicator of clean fleece weight.
