| 摘 要： | 研究采用PCR—SSCP技术研究番鸭不时就巢群体（就巢1月群、就巢2月群、就巢3月群）、番鸭非就巢群和白改鸭5个群体250个个体PRL三基因第4外显子多态性与就巢性状之间的相关性。结果表明，在外显子4编码区内发现2个SNP位点，分别位于该基因的3777 bp（T/C）和3785 bp（A／G）处。基因型与就巢性状指标相关分析的结果表明，番鸭非就巢群体与各就巢群体间差异极显著（P〈0．01），同时番鸭与白改鸭差异显著（P〈0.05），推测PRL基因与就巢性有一定的相关。

| Abstract: | PCR-SSCP technique was used to analyze the polymorphisms at the exon 4 of the PRL gene in 250 individuals among five duck populations (non-broodiness muscovys,one month broodiness,two months broodiness and three months broodiness muscovies, and Baigai ducks) to further investigate the correlation between polymorphism and broodiness traits.The results showed that there are two SNP sites in the fragment of exon 4,locating at 3 777 bp (T/C) and 3 785 bp (A/G),respectively.There were significant differ- ences b... |
