Pit-1/Hinf Ⅰ基因PCR-RFLP和鲁西黄牛与利木赞杂交牛生长性状的关联性分析
Associations of PCR-RFLP in Pit-1/Hinf Ⅰ Gene with Growth Traits in Hybrid Cattle of Luxi Yellow Cattle and Limousin
摘要
Abstract
Improving the grouth level and meat production of Luxi Yellow Cattle, this paper use PCR-RFLP technology to analysis the correlation of Pit-1 gene polymorphism and growth traits of 111 hybrid cattle of Luxi Yellow Cattle and Limousin. The results show that the Pit-I-Hint I loci of 451 bp's PCR products is polymorphism after enzymes Hint I enzyme,the allele frequency of A and B were 0. 32 and 0. 68 ,it is not fit for Hardy-Weinberg balance. The rump length of AA genotype is higher than AB and BB genotype within population (P <0.01) ,it can be used one of candidate genes;The hip width of AB genotype is higher than AA and BB genotype (P <0.05) within the group; But there are no differences among 3 genotypes in the head length, forehead width , chest circumference , chest deep and wide, body length , rump length , waist angular wide , shank circumference, body height, the cross department high,the hip higher (P >0.05).关键词
