【摘要】：试验通过寿光鸡和快羽系琅琊鸡进行测交,观察后代中羽速和羽色的表型和分离比例。选择具有纯合基因的快、慢羽兼具黑色素扩散基因的寿光鸡作为亲本,建立快慢羽纯系系谱F1代。选留F1代快羽公鸡与慢羽母鸡建立自别雌雄配套系。结果表明,黑羽对麻羽的遗传方式是完全显性遗传;快慢羽纯系后代快、慢羽比例分别达到99.72%和99.76%以上;羽速自别雌雄准确率公雏99.85%以上,母雏99.77%以上。
[Abstract]:In order to observe the phenotype and segregation ratio of feather speed and feather color in progeny, the experiment was carried out with Shouguang chicken and fast feathering line Langya chicken. Shouguang Chicken with homozygous gene, slow feather and melanin diffusion gene was selected as parent to establish F1 generation of fast and slow feather pure line. F 1 fast feathering cock and slow feathered hen were selected to establish their own female and male mating lines. The results showed that the genetic pattern of black feather to hairy feather was completely dominant, and the percentage of slow feathering was 99.72% and 99.76%, respectively. The accuracy rate of male and female is over 99.85%, and that of female is more than 99.77%.
