摘要
收集专门化品系A系兔第六世代兔生长发育测定资料 ,应用Harvey(1990 )程序进行统计分析 ,估计其遗传参数 ,结果为 :生长性状属高遗传力性状 ,h2 =0 415 - 0 5 76。各体重性状间大部分呈显著、极显著遗传相关 ,rA=0 390 - 0 816 ,因而可利用早期体重进行间接选择而达到预期目的。大部分体重性状与各阶段日增重也呈显著或极显著相关。
In the study, the growing data about the sixth generation of strain A of rabbit were collected in the breeding rabbitary of Sichuan Provincial Animal Science Academy. The genetic parameters were evaluated by using the programme of Harvey (1990). The results are as followed: The heritabilities of growing characters are high, h2=0.415-0.576. There are significant or VERY significant genetic correlations between major body weight traits, r A=0.390-0.816. So we can use body weight at early days for indirect selection to achieve the expected goal. The majority of ADG traits are significantly or very significantly correlated with body weight.
