Abstract. Accounting for the assessment of winter hardiness showed no damage in the studied varieties. Phenological observations made it possible to establish a genetic regularity of the duration of the phenological phases, including the timing of their onset. Sortoobraztsy received on the basis (carpal х virgin, virgin, Siori) begin to bloom for 2 weeks later varieties of specimens obtained from carpal cherry. The same picture is also observed with a later passage of phenophases in terms of the periods of flowering, maturation, and the onset of leaf fall. Dessert taste was noted in the variety of Olgin's Joy (selections of CSB SB RAS, Novosibirsk). The cultivars of carnivorous carp (f. Plena, Meteo, Colorata), as well as the virgin (Schubert), had a mediocre taste of fruits (3.8‒3.9 points) and less mass (0.5‒0.6 g). The best fruit quality indices were found in selected seedlings of virgin bird‒cherry seedlings No. 1 and No. 2, Salamatova Memory grade, both in diameter of fruits (0.9‒1.3 cm) and in weight of berries (1.0‒1.3 g). Accounting for productivity indicators allowed to establish that the Salamatova Memory grade had larger brushes and the number of berries on the brush (14 pieces). It should be noted the change in the productivity of the variety samples, depending on the genetic origin. The varieties belonging to the carnivorous carp have lower indicators of the weight of the brush, the number of berries on the brush and the mass of 100 berries, and the samples obtained with the participation of the virgin bird‒cherry (Virgins No. 1 and No. 2) had higher productivity indicators. It was revealed that the Schubert variety had the lowest productivity indicators by experience. Evaluation of the growth force, it was possible to isolate the most vigorous varieties: Colorata (2.5 m high and 2,1 m3 crown volume), Purple candle (2.4 m and 2,2 m3 respectively), Virginia No. 2 (2.4 m and 2.8 m3). In the ornamental form of carnivorous carp (f. Pleno), the height and volume of the crown were minimal in experience – 1.3 m and 0.5 m3 . At the same time, a more compact crown is typical for the Virgine No. 1 and Chemalsky luxury varieties (the volume of the crown is 0,6 m3). Based on the conducted primary studies on the introduction of bird‒cherry, the best sorts for a variety of economic and utility traits are the varieties of virgin bird-cherry (Virgins No. 1 and No. 2) and the variety of Salamatova Memory.
