摘　　要：通过分析丝羽乌骨鸡白羽母系选育第六、七世代开产日龄、开产体重、开产蛋重,作开产日龄、开产体重、开产蛋重之间相关分析和两世代产蛋性能的均数差异显著性检验和相关分析。结果表明,两世代开产性能有极显著差异;开产体重与开产蛋重、开产蛋重与开产日龄、开产体重与开产日龄均呈显著正相关(相关系数分别为0.32246、0.32942、0.21078,P<0.01)。With the data of the average age at first egg(AFE),body weight at first egg(BWT) and egg weight at first egg(EWT),we had the sixth generation's and the seventh generation's statistic material do correlation analysis between AFE、BWT and EWT. The results showed that the correlation coefficients of BWT & AFE,EWT & AFE and BWT & EWT were all very significant (P<0.01), and there was very significant difference between the two generation's first layer performance.
