摘要
以鸡VIPR-1基因作为早期产蛋性状的候选基因,选取了12个多态位点对644只宁都三黄鸡进行基因型检测并分析了其与早期产蛋性状的相关性。研究表明:位于5′调控区的位点A-284G与开产日龄(P<0.0001)、总畸形蛋数(P<0.05)呈显著相关,等位基因G有利于产蛋量的提高;位于内含子6的位点C+42913T与300日龄产蛋数和300日龄的总正常蛋数显著相关(P<0.05),CT基因型为优势等位基因型;位于内含子8的位点C+53327T与开产日龄呈极显著相关(P<0.01),等位基因C有利于开产日龄的提前。
In this study,vasoactive intestinal peptide receptor-1（VIPR-1） gene was used as a candidate gene to analyze the association of 12 polymorphisms sites with early egg production traits in 644 individuals in Ningdu Sanhuang population.Association analyses showed that the A-284G in the 5′ regulatory region was significantly associated with the age of first egg（P〈0.000 1） and total number of oafish egg from 90 to 300 d of age（P〈0.05）.Allele G is positive for number of egg.The C＋43 327T in intron 6 was significantly associated with total number of eggs and total number of qualified eggs from 90 to 300 d of age（P 〈0.05）.CT was predominant genotype.Significant association was also found between C＋53 327T in intron 8 and the age of first egg（P〈0.01）.The allele C was positive for less age of first egg.
