Abstract:

The genetic diversity and genetic structure of Jinnan cattle,Jiaxian Red cattle,Luxi cattle and Qinchuan cattle were detected by microsatellite technology.Allele frequencies and distribution of 16 microsatellite markers were detected in 4 cattle populations.Number of effective alleles of the other 15 loci was from 2 to 8 except HEL9 as a monomorphic loci in all individuals,and the average number of effective alleles was 3.067 6.BM1818 was low genetic polymorphisms (PIC=0.083 0,PIC<0.25),and the others were high genetic polymorphisms (PIC>0.5),with the highest PIC value at HUAT24 locus (PIC=0.727 5).80 alleles were identified in 4 populations (63 alleles in Jinnan cattle,65 in Jiaxian Red cattle,65 in Luxi cattle and 68 in Qinchuan cattle,respectively).The allele B at IDVGA46 was detected only in Jinnan cattle,and the allele B at TGLA44 was only lack in Jinnan cattle.Mean observed heterozygosity,mean expected heterozygosity and mean heterozygosity were 0.385 2,0.640 3 and 0.578 0,respectively in 4 populations.Jinnan cattle was independently clustered in the NJ tree and the genetic distance (DA) with Luxi cattle,Jiaxian Red cattle and Qinchuan cattle were 0.809 3,0.759 8 and 0.807 1.There were special genetic characterics and sufficient genetic diversity in Jinnan cattle,and it was a relatively closed population in its evolutionary process.
