Abstract. The need for constant updating of the plum assortment in the foothills of Kabardino-Balkaria is caused by the imperfection of cultivated varieties. In this regard, we are conducting a variety study of varieties of homemade plum for the subsequent selection of the best of them. As a result, cultivars with the best in a number of valuable features and properties were identified. One of the important indicators for the comparative assessment of the studied plum varieties in the conditions of the region are the flowering time, yield and commercial qualities of fruits, as they characterize the resistance of the variety to adverse factors and its economic efficiency. Medium- and late-flowering varieties are considered more valuable, due to the fact that they escape the destructive effects of recurrent frosts and, as a rule, are characterized by regular fruiting. Milena, Early Hermenchik, Fortuna, October Sun, Top Hit, Byron Gold and the Grand Duke are among the studied cultivars with a late onset of flowering. In the middle term, they bloom – Big Prince, Kyrgyz excellent, Kuban comet, Kabardian early, Top Giant, Angelino, Black Star. All the studied varieties entered the period of full economic fruiting and began to yield high yields. In this regard, varieties with yields in terms of 1 ha are qualitatively distinguished: Kyrgyz excellent – 54 t/ha, Kabardian early – 35.3 t/ha, Top Giant – 34 t/ha, Byron Gold – 33.6 t/ha, Top Hit – 32.8 t/ha, Grand Duke – 32.1 t/ha, Chachak early – 31.9 t/ha, Big Hart – 31.5 t/ha, Ti chi san – 31.3 t/ha. A characteristic varietal feature is the size of the fruit, although to a large extent it depends on the growing conditions, the agricultural technology used, the age of the tree, the load of its harvest, rootstock and a number of other factors. Varieties have high fruit weight indicators: Ti chi san – 98,8 g, Angelina – 91,4 g, Top Giant – 90,1 g, Grosso de Felicio – 86,5 g, Byron Gold – 83,9 g, Oktouber San – 68,9 g, Kabardian early – 62,5 g, Yellow large – 56,4 g, Grand Duke – 52,6 g, Yellow Afaska – 42,3 g.
