摘要: 为了提高鲁西黄牛生长发育水平及产肉性能。利用PCR-RFLP技术研究111头利鲁杂交牛Pit-1基因多态性与体尺生长性状指标之间的相关性。结果表明,群体的Pit-1-HinfⅠ基因座的451 bp的PCR产物被限制性内切酶HinfⅠ酶切后表现多态性,它们的等位基因A、B频率分别为0.32,0.68,不符合Hardy-Weinberg平衡状态。群体Pit-1基因座不同基因型与体尺生长性状指标相关分析的结果表明,群体内AA基因型个体的尻高显著高于群体AB和BB型个体(P<0.01),可作为利鲁杂交牛尻高的候选基因之一;群体内AB基因型个体的髋宽显著高于群体AA和BB型个体(P<0.05);但在头长、额宽、胸围、胸深、胸宽、体斜长、尻长、腰角宽、坐骨结节宽、管围、体高、十字部高、臀端高等指标上均无显著差异(P>0.05)。

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-1-HinfⅠ loci of 451 bp′s PCR products is polymorphism after enzymes Hinf 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(P0.01),it can be used one of candidate genes;The hip width of AB genotype is higher than AA and BB genotype(P0.05) 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(P0.05)

Key words: Pit-1, PCR-RFLP, Growth traits, Hybrid cattle of Lilu
