摘要
对105只6月龄塞北兔的体重、体尺、耳型进行了通径分析。结果表明:塞北兔6月龄体重与体长、胸围、耳长、耳宽的相关系数依次为0.730、0.736、0.465、0.354,通径系数依次为0.526、0.535、0.264、-0.148;通过对决定系数与相关原因决定系数的分析,决定系数总和为0.849,误差项决定系数为1~0.849,并建立了塞北兔成年体重的“最优”回归方程。
The weight, body dimention and ear type were studied on Saibei rabbits agdein 6 - month by path analysis. The results showed that the correlative coefficients between weight and body length , chest girth, ear length , ear width were 0. 730, 0. 736, 0.465 and 0. 354 reparately. Path coefficients for them were 0. 526, 0. 535, 0. 264 and - 0. 148. The sum of the determination was 0. 849, and the error coefficients was 1 - 0. 849 by analyzing determination coefficients. The best linear regression equation about rabbit of Saibei rabbit was established.
