| 摘 要： | 分析獭兔KAP基因和FGF5基因的多态性与经济性状的关系,为獭兔下一步的性状改良提供理论基础.利用PCR-SSCP技术对KAP基因的4个位点进行遗传变异检测,通过SPSS软件下的GLM程序分析150只獭兔KAP基因2个多态位点及FGF5基因2个多态位点不同基因型的最小二乘均值(LSM)、最小二乘效应值(LSE)及其遗传方差;通过标记位点与胴体性状和毛皮性状的遗传相关预测了选择反应.结果表明:獭兔KAP3.2位点可作为胴体深和被毛密度的标记位点,KAP6-1位点可作为獭兔体质量,胴体质量和被毛长度性状的标记基因型的标记位点,FGF5-1位点可作为体质量、胴体质量、皮质量和被毛密度的标记位点.

| Abstract: | Rex rabbits genetic polymorphism of KAP and FGF5 gene was studied and the relationship between polymorphism loci and economic traits was analyzed in order to find molecular marker of MAS,providing theory basis for next molecular breeding. The polymorphism of genes was studied u-sing PCR-SSCP. The least square mean (LSM) , the least effect (LSE) and genetic variance of different genotype at 4 polymorphism loci were analyzed,using GLM procedure of SPSS software. The selection reaction was forecasted by genetic correlation between marker loci and genetic variance of economic traits. The results showed that; KAP3. 2-BB were the favorable marker genotypes for Rex rabbit thoracic deepth and wool density traits, FGF5-1-AA were the favorable marker genotypes for Rex rabbit body weight, carcass weight, tare weight and wool density trait. FGF5-3-AA could be used as the best marker genotypes for Rex rabbit body weight, carcass weight and the wool length trait. |
