摘　　要：用ｈａｒｖｅｙ软件中的ｍｏｄｅｌ４对湖北红鸡Ⅰ、Ⅲ系的三、四世代资料进行遗传分析。开产日龄、开产体重、４０周龄产蛋数、４０周龄蛋重的遗传力分别为：０．２６，０．４２，０．２１和０．５２。４０周龄产蛋数与开产日龄、开产体重、４０周龄蛋重的遗传相关分别为：－０．６４７～－０．７２７，０．００７～０．１４７和０．４３１～－０．４４９。Data of 3th and 4th generation of line 3 and line 4 of Hubei-Red chickens were analyzed by Harvey programme′s model 4. The heretability of egg number of 40 weeks of age,age of first egg,body weight at 1st agg,egg weight at 40 weeks of age were 0.26,0.42,0.21,0.52 respectively.Genetic corralation coefficients between egg number of 40 weeks of age with age of 1st egg,body weight at 1st egg,egg weight at 40 weeks of age are -0.647——-0.727,0.007—0.147,-0.431——-0.449 respectively.
