By crossbreeding to transfer the genes of high coarse-wool rate in French Angora rabbit,New Zealand rabbit and SAB white rabbit into German Angora rabbit,the academies of Agricultural Sciences of Jiangsu,Zhejiang and Anhui have bred Su I strain,Zhe strain and Wan Ⅲ strain resp.After 5 generations successive breeding,the three new strains coarse-wool rabbits whose heredity is basically stabilized have the characters of higher coarse—wool rate and higher wool yield. Su Ⅰ strain:The coarse-wool rabbits have an average coarse-wool rate of 15.71%,annual wool yield 898g and adult(11 mths)weight 4505g.The heritabilities of coarse-wool rate and wool yield are resp 0.1340 and 0.2950. Zhe strain:The average of coarse-wool rate,annual wool yield and adult(11 mths)weight of the coarse-wool rabbits are 15.94%,959g and 4033g.The heritabilities of coarse-wool rate and wool yield are 0.1312 and 0.2648. Wan Ⅲ strain:The average coarse-wool rate of the coarse-wool rabbits is 15.14% The annual wool yield is 1012g.The adult(11 mths)weight is 4117g.The heritabilities of coarse-wool rate and wool yield is 0.2124,0.3296 resp. The genetic correlation coefficient between coarse-wool rate and wool yield,body weight and coarse-wool rate,body weight and wool yield are all positive,which indicates the plan and the technical routine used in coarse-wool rabbit breeding are feasible. There are now 1817 rabbits as the nucleus herds with an average coarse-wool rate of 15.60%,annual wool yield 956g and adult(11 mths)weight 4215g,6000 rabbits as the breeding group and over 100,000 rabbits as the production group.All above have reached or exceeded the estimated targets.
