The article presents the results of the study of grapevine genetic resources at Don Ampelo-graphic Collection named after Ya.I. Potapenko (Novocherkassk, Rostov re-gion). In 2016–2020, agrobiological, uvologi-cal, chemical and technological study of 9 ta-ble varieties and 2 technical varieties of the Moldovan breeding was carried out. The pur-pose of the research was to determine the adaptive potential of varieties in the condi-tions of the Lower Don region and to accu-mulate material for the database. According to the complex of economically valuable signs (a high percentage of blooming eyes, fruit-bearing shoots, yield, sugar and acid content, organoleptic assessment), the following varie-ties stand out: Skorenskiy krasnyy, Moldova, Zvezdnyy, Vierul–59, Marshalskiy. The tech-nical variety of Norok was distinguished by the productivity and high quality of the wine, the wine tasting score was 8.7 points. The Pyfos variety can be recommended for selec-tion for winter hardiness (the safety of the eyes is 97.6 %) and productivity (the percent-age of fruitful shoots is 90.7, and the coeffi-cient of fruitfulness of shoots is 1.6).
