【摘要】 收集专门化新品系A系兔第 4、5世代繁殖资料 (共计 75 3窝 ) ,应用Harvey(1 990 )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 0 89～ 0 1 6 7范围内 ,其重复力也较低 ,为 0 1 1 9～ 0 1 93。绝大多数繁殖性状之间存在较强的遗传相关 ,rA=- 0 4 1 5 - 0 974。更多还原

【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, r A=-0 415-0 974。更多还原
