Plant and Fungal Species Descriptions

Understanding genetic traits of seven seedless King mandarin accesions discovered 2013 at Hau Giang, this study was based on the matK region to discriminate among them and with other common King mandarin trees especially the seedlees King mandarin LD6 accession based on the matK region. The pair of primers matK-390F/matK-1326R was used to amplify the matK region of these accessions. The results of matK sequence showed a genetic diversity of King mandarin accessions studied, that is the 7 seedless accessions had different nucleotide positions not only among themselves but also with other common King mandarin accessions especially LD6 accession. Based on the phylogenetic tree, studied King mandarin accessions could be grouped into 2 branches of bootstrap ranged from 22 to 75%: branch I included the seedless King mandarin accessions and branch II contained two seedy King mandarin. This genetic diversity in matK sequence could be used to distinguish 7 seedless King mandarin discovered in Hau Giang and with other common King mandarin especially with LD6 accession.
