One-year shoots are medium thickness, straight, reddish-brown on the sun-exposed side, greenish on the shaded side. Fruit wood forms on branches of two to three years old as clusters and on one-year growth of varying lengths. Buds are arranged in threes, occasionally singly, conical in shape, set apart from the shoots. Tree is strongly branched. Leaves are large, egg-shaped with a pointed tip. Leaf length 9.5 cm, width 8 cm, sometimes length does not exceed width. Leaf blade thin, smooth, matte. Leaf margin finely toothed, slightly pointed and curled at the tip. Upper leaf surface densely green, lower surface pale. Petiole 3 cm, medium thickness, reddish-purple. Flowers large, pink. Petal shape rounded, degree of closure weak. Calyx shape cup-like. Stigma higher than stamens.

Fruits are densely arranged within the crown and firmly attached to branches. Average fruit weight 26.2 g, maximum 32.4 g, height 38 mm, diameter 36 mm. Shape oval-elongated, tapering to a beak-like tip. Fruit sutures are fine, marked by an intensely colored stripe. Fruit stalk is very short (0.3-0.5 cm), thick.

Fruits suitable for fresh consumption and technical processing. Transportability medium. Sensory rating of fruits 3.5 points. Stone completely free, medium size, round, slightly elongated toward the apex, flattened on the sides, surface smooth. Kernel sweet.

Trees enter fruiting stage in the third to fourth year of life. Variety capable of annual fruiting. Commercial yield forms from the fifth year onward. Relatively resistant to moniliosis. Fruit ripening period August 10-15. During rainy periods, fruits do not crack.

Advantages of the variety: resistance to moniliosis and drought. High winter hardiness and annual fruiting capacity.

Disadvantages: frost damage when grown on low-lying areas with high moisture. Insufficient fruit size.
