摘　　要：利用皖系粗毛型长毛兔选育资料，进行约束指数估计遗传进展的预期值，并建立约束选择指数。经分析，当选择无约束时，复合育种值进展呈现最高（ΔＨ＝２．８８４１），但目标性状进展则随约束的使用而增大。因而，为了提高产毛量的遗传进展，可设定约束指数，限定体重或粗毛率或同时约束，使产毛量迅速提高。This paper established the formula of restrict selection index of coarse wool rabbit based on the developing date of Wan strain of coarse wool rabbit.The resultes showes that the genetic improvement of wool yield is larger when restricting separately the improvement of body-weight or the coarse wool rate and it is largest when restricting the improvement of body-weight and the coarse wool rate.To speed the genetic improvement of wool yield and keep indecreasing of improvement of coarse wool rate.Using the restricting formula is suitable.
