摘　　要：本研究根据现代遗传学基因测交理论,共用32只表型慢羽公鸡与245只快羽母鸡组成测交试验。结果表明,所测的32只公鸡无一只为纯合慢羽基因型。但发现测交后代的快慢羽分布比例与孟德尔遗传上的分离定律完全吻合。同时通过混合精液输精,实施扩群繁育,其中选留慢羽种母雏1460只,表型慢羽种公雏150只,从而为建立隐性白鸡慢羽系奠定了基础。Based on the gene-cross theory of modern genetics, we chosed slow-feathering male chicken (32), and fast-feathering hen (245) to carry out the test. After crossing,we found that none of the 32 male chickens was pure slow-feathering gene type.But the result accorded with Mendel'genetic rules. And by mixing semen and breeding,we selected slow-feathering female chicks, 1460,and slow-feathering male chicks, 150,which were the base of creating a slow-feathering line of recessive white feather chicken.
