| 摘 要： | 目的对中国地鼠山医群体近交系E的一些繁殖性状进行遗传力估计分析。方法采用平均信息约束最大似然法（AIREML）,利用WOMBAT软件进行处理。结果产仔数、离乳数、胎间隔2-1和胎间隔3-2的遗传力均较低,分别为0.05、0.096、0.182和0.116。结论中国地鼠山医群体近交系E繁殖性状的遗传力均属于低遗传力。

| Abstract: | To understand the genetic characteristics of Shanyi colony inbred strain E of Chinese hamster,the reproduction records of Shanyi colony inbred strain E of Chinese hamster in 2001-2010 were used to estimate the heritability of the reproduction traits by the method of average information restricted maximum likelihood（AIREML）.The results showed that the heritability of the litter size,weaning number,birth interval 2-1,birth interval 3-2 was low,with the value of 0.05,0.096,0.182 and 0.116,respectively. |
