摘　　要：对不同深浅羽色甘肃黄鸡的主要产蛋性状作了观测，结果表明：甘肃黄鸡羽色深浅对蛋用性能没有影响；蛋壳颜色勺蛋壳厚度、哈氏单位和母鸡产蛋量有显著的相关关系；甘肃黄鸡今天产蛋较为分散，生产中应适当推迟集蛋时间；蛋壳颜色与鸡群产蛋时间可以作为甘肃黄鸡产蛋量选择的辅助指标。Main egg laying traits were measured on Gansu Yellow Chicken varied fromlight feather to dark featheL The results showed that there was no relationship between feathercolor and egg traitsj; however, there were significantly relationships between the eggshell colorand the eggshell heigh, and Hunt unit and the egg number Laying time in a day was relativelydispersive and the time of egg gathering should be put off under practical condition. Eggshellcolor and laying time of the flock could be regarded as assistant index for egg number selection ofGansu Yellow Chicken.
