摘要

BMY cattle (1 /2 Brahman, 1/4 Murray Grey and 1/4 Yunnan Yellow cattle) has been inter se breeding since 1980s. Genetic diversity of BMY cattle was extensively investigated using 16 rnicrosatellite markers. A total of 130 rnicrosatellite alleles and high allele size variance were detected. All loci displayed high genetic diversity with overall mean of N_a = 8.13, PIC = 0.7224 and H_e = 0.7666, which were higher than those of many other beef breeds. The allele-sharing neighbour-joining tree clearly displayed the new genotypic combinations and the minglement from both BMY cattle and Brahman. The results provided the genetic information to match the standards of new beef breed in South China.
