In Ukraine, the areas allocated to garlic cultivation are expanding and as of 2020 amounted to 1,100 hectares, which is driven by high profitability and steady demand in both domestic and foreign markets. At the same time, the evaluation of current and new varieties of winter garlic is important for further yield increase in this valuable crop. The purpose of the study is to evaluate the genetic diversity of the studied varieties of winter garlic by ISSR loci and determine the most productive ones in the conditions of the Left-Bank Forest-Steppe of Ukraine. Winter garlic varieties Dyushes, Lyubasha and Ugorskyi (line 20-16) were used for the research. The largest marketable yield (14.1 t/ha) was obtained by growing winter garlic of the Lyubasha variety. The Ugorskyi variety (line 20-16) provided a yield of 12.9 t/ha, the Dyushes variety 9.4 t/ha. The formation of the yield of winter garlic by 12.3% depended on the characteristics of the variety, the impact of the growing season made up 87.3%. The variety of winter garlic Ugorskyi (line 20-16) with As = 73.8% was agronomically stable (As ˃ 70%). Based on the above studies, allelic formulas (molecular genetic passports) of winter garlic varieties Ugorskyi (Line 20-16), Lyubasha and Dyushes were formed. The studied varieties of winter garlic contained several amplicons unique within the group under investigation. In the Dyushes variety, the unique loci were UBC812725 and UBC 812902, and in the Lyubasha variety UBC 812791 and UBC 842702. The 20-16 line had the most unique loci: UBC 812460, UBC812997, UBC826682, UBC8341283, and UBC846920. The calculated Nei-Li similarity coefficients indicate a close genetic distance between studied varieties of winter garlic. The varieties Lyubasha and Dyushes are genetically closer to one another compared to Ugorskyi (line 20-16)
