The aim of the present work was the DNA fingerprinting of a number of promising grapevine cultivars of NCRRIH&V and AZESV&W breeding, based on the analysis of polymorphism of microsatellite loci. The results of the study can be used for identifying of the studied cultivars and for control purebred of parent vines plantations and planting material of domestic cultivars. Domestic breeding cultivars, promising to improve the industrial assortment of grapes in the Southern Russia were studied on the molecular genetic level. The article presents the results of a DNA-fingerprinting of six domestic cultivars of grapes: Barchatny, Vladimir, Dmitry, Dostoyny, Kurchanskiy, Krasnostop AZOS. Analysis of cultivars genotypes carried out on the mixture of DNA samples of 7-10 typical plants of each cultivar. DNA profiles were obtained by microsatellite loci MD5, VVMD7, VVMD27, VVS2, VrZAG62 and VrZAG79, these markers are recommended as the basic ones for Vitis vinifera L. genotyping. Microsatellites (SSR-simple sequence repeats) - tandem repeats of simple sequences in the DNA structure are the most often used as DNA markers for studying of the grapes genotypes. The main method used in the work - polymerase chain reaction with the separation of the reaction products using an automated genetic analyzer ABI Prism 3130. The DNA of Chardonnay and Cabernet Sauvignon were used as the control, allelic compositions of studied SSR-loci are known for these cultivars. Cultivars genotypes showed the different alleles combinations on studied loci. Thus, the minimum recommended set of microsatellite markers is sufficient to differentiate of studied genotypes. The article also provides a brief description of the studied cultivars and their main distinguishing positive agric and biological characteristics.
