Abstract

Genetic diversity of Luxi cattle was evaluated by the microsatellites markers.6 pairs of primers out of 30 microsatellite loci were tested which were recommended by the UN Food and Agriculture(FAO) and the International Animal Genetics(ISAG) in 112 individual microsatellites,a total of 101 alleles were detected.The number of alleles per locus was from 4 to 6,the average allele number,effective allele number,observed heterozygosity,expected heterozygosity and polymorphism information content for the population sampled were 4.67±0.82,2.54±0.64,0.59±0.09,0.41±0.09 and 0.53±0.09,respectively.All Parameters had almost reached the rich standard of genetic diversity.The results may provide a scientific basis for the study of characteristics of Luxi cattle breeds so as to preserve and utilize them.
