摘要: 收集专门化新品系A系兔第4、5世代繁殖资料(共计753窝),应用Harvey(1990)程序进行统计分析,估计其遗传参数,结果为:繁殖性能遗传力较低,各性状的估值不同,在0.089~0.167范围内,其重复力也较低,为0.119~0.193。绝大多数繁殖性状之间存在较强的遗传相关,rA=-0.415-0.974。

Abstract: In the Study,the data of 753 litters of the fourth and the fifth genenation of Strain A of rabbit were collected in the breeding rabbitry of Sichuan Provincial Animal Science Academy to esstimate the genetic parameters of reproduction traits. The results are:the heritabilites of reproduction traits are low with the range from 0.089 to 0.167; the repeatability is between 0.119 and 0.193. There are strong genetic correlation among the majority of charactors, rA=-0.415-0.974。
