摘  要:
本文对440头一岁半敖汉细毛母羊毛长、污毛量和剪毛后体重几项主要经济性状的表型参数和遗传参数进行了估测.其中平均污毛量为6.7718±1.2305公斤,平均体重为39.3588±4.5771公斤,平均毛长为8.9655±0.8285厘米;污毛量,体重、毛长的遗传力分别为:0.3265、0.4836、0.5239。重复力分别为:0.5269、0.4569、0.6152;毛长和体重、污毛量和体重、污毛量和毛长的遗传相关分别为:0.002011、0.2668、0.1225,表型相关分别为;0.0139、0.3299、—0.0839.

摘  要:
The articse presents mainly phenotype parameter and genetic parameter of the staple length, grease-flcece weight and body eight after being sheared in Aohan Merinos.The material was obtained on the basis of the Aohan sheep breeding property in 1979-1980.The ewe's average staple length was 8.9655±0.8285cm the average of grease-fleece weight 6.7718± 1.2305kg, the average of body weight after sheating 39.3588 ± 4.5771 kg. the heritbility of the staple length, the greasc-fleece weight and the body weight after shearing was 0.5239, 0.4836 and 0.3265 respectivcly.The repeatability of the staple, grease-fleece weight and body weight after sheareding was 0.6125, 0.5289 and 0.4569 respectively. Genetic correla tions between staple length×and body weight grease-fleece weight×and body weight and staple length×and grease-f leece weight was 0,00211, 0.2666 and 0.1225 respectively,Phenotype correlations among them was 0.0139, 0.3299 and-0.0839 respectively.
