【摘要】 利用通径分析的原理和方法，对皖系粗毛型长毛兔选育群三、四、五世代１１月龄粗毛率进行通径分析。结果发现５、８、１１月龄粗毛率分别为１０．７３±１．３３％、１２．５６±１．７５％、１３．０５±２．０７％，相互呈中等以上正相关；５、８月龄粗毛率与相应的体重、产毛量呈弱负相关（Ｐ＜０．０５）；１１月龄粗毛率与相应的体重、产毛量相关不显著（Ｐ＞０．０５）；直接影响１１月龄毛率最大的性状是８月龄粗毛率，其相关和通径系数较高（ｒ（ｙｘ６）＝０．７０３４，Ｐ（ｙｘ６）＝０．），其次为５月龄产毛量和粗毛率，其他性状影响较小。因此，选育粗毛型长毛兔应以８月龄粗毛率为主要选种依据。更多还原

【Abstract】 According to the priciple of path analysis,the coarse wool rate of 11 month were anal-ysed in third,fourth and fifth generation of Wan Strain Coarse Wool Angora Rabbit.Itshowed that the coarse wool rate of 5,8 and 11 month were 10.73%,12.56%and 13.05%respectively,there was medium direct-correlation between them. There was weak negative-correlation between the coarse wool rate and their body weight,wool yield at 5 month or 8month(P<0.05).The wasn’t significant correlation between the coarse wool rate and theirbody weight,wool yield at 11 month(P> 0.05 ).The most immediate cause affecting thecoarse wool rate of 11 month was that of 8 month,both the correlation coefficient and pathcoefficient were the highest(r(yx6)=0.7034,P(yx6)=0.6730),and then wool yield and thecoarse wool rate at 5 month,and Other characters’effect was weaker.So the coarse wool rateof 8 month was the major basis in selecting coarse wool Angora rabbit.更多还原
