Evaluation of Crossbreeding Effects for Wool Traits in Sheep

Crossbreeding effects for wool quality traits viz. greasy fleece weight (kg), staple length (cm), average fibre diameter (μ) and medulation percentage were estimated using the Dickerson’s and Kinghorn’s models. The data analyzed involved 15 genetic groups including Nali purebred, F1’s of two and three breeds, F2’s and reciprocal crossbred obtained from the crossing of Nali (N), Merino (M) and C...
