摘　　要：通过对550只固始鸡G2系母鸡8周龄、18周龄及开产体重的分析,结果发现:8周龄体重与18周龄体重、8周龄体重与开产体重以及18周龄体重与开产体重之间均存在着中等以上强度的相关关系,其相关系数分别为0.5583,0.3916,0.6776。在此基础上,建立了两个周龄与体重之间的直线回归方程,为固始鸡的育种工作提供了参考依据。According to the correlative analysis among body weights of Gushi layers at8,18week-age and first laying period,the results showed:there were above-middle strength correlativity between body weight of8week-age and18week-age,between body weight of8week-age and first laying period,between body weight of18week-age and that of first laying period.Their correlative coefficients were0.5583,0.3916and0.6776respectively,Based on this,linear regressive equations between two body weights of different week-age and that of first laying period were set up.
