摘　　要：选用20对微卫星标记对120只文昌鸡进行多态性检测,分析微卫星标记与产蛋性能的关系。结果表明:①文昌鸡群体内遗传差异较大,遗传多样性丰富;②位于4号染色体的标记LEI0119与55周龄蛋重显著相关(P<0.05),位于2染色体的标记MCW0131及位于Z染色体的标记MCW0294与400日龄产蛋数呈显著相关(P<0.05)。研究结果可为文昌鸡的保种和选育提供理论依据。Based on the polymorphisms of 20 mierosatellite markers and data generated from the experiment,the relationships between microsatellite loci and egg production（400 d）,egg weight were analyzed. The results showed that：①The genetic difference was significant in Wenchang chicken; ②The correlation between egg weight at 55 weeks age and LEI0119 Marker was significant （P〈0.05）.Another two significant correlations were found：for MCW0131,MCW0294 and egg production（400d） （P〈0.05）.
