Abstract:

In order to evaluate the genetic structure in Yunshang Black goat at the molecular level,108 Yunshang Black goats from 10 families,11 Yunling Black goats,14 Nubian goats and 10 Boer goats (control group) were genotyped by Illumina Iselect Goat60k array (SNP chip).Genetic diversity parameters statistics,principal component analysis and phylogenetic tree construction were performed by GenAlEx 6.5,Cervus 3.0,SNPRelate,Plink 1.07 and Mega 4.0.The typing results at 48 116 SNPs loci in 143 samples had been gotten.There was a great genetic distance between Boer goat and Yunshang Black goat,and a large genetic distance also existed between Boer goat and Nubian goat.Bore goat was displayed as an independent branch on the cluster tree.The results proofed the method of this study was practical and reliable.108 samples of Yunshang Black goats were high consistency,and these samples were clustered into a large cluster in the phylogenetic tree.The samples of Nubian goats (14) and Yunling Black goats (11) were clustered into a cluster.UPGMA evolution tree displayed that Yunshang Black goats were closely related to Nubian goats,and had a little relationship with Yunling Black goats,which was consistent with the results of the breeding blood guide in Yunshang Black goat.Yunshang Black goat could be distinguished from the breeding material at the genomic level,which had genomic characteristics of an independent variety.
