摘要

The objectives of the present study were to estimate the allele and genotype frequencies of the POU1F1/HinfI polymorphisms in beef cattle belonging to four different genetic groups and to determine the effects of these polymorphisms on growth traits in cattle. The 451-bp PCR products of POU1F1 gene digested with HinfI exhibited three genotypes and two alleles, which were at Hardy-Weinberg equilibrium (P0.05). Genotype BB was the predominant genotype and B the predominant allele in the studied populations. There was significant difference between LimousinQinchuan and Qinchuan in the distribution of genotypes (P0.0001). The association of the polymorphism of the POU1F1 gene with growth traits among Qinchuan, LimousinQinchuan, AngusQinchuan and Germany YellowQinchuan crosses was analyzed. Body weight and wither height of individuals with genotypes AB were higher (P0.05)than that of individuals with genotype BB in the Germany YellowQinchua cross, but were not in the other three populations (P0.05).
