Pedicel length 13 mm, medium, unpubescent.
Fruit round, equilateral, large — height, width and thickness 37 mm, weight 38 g. Main color light green, covering color pink-red, completely covering the fruit, no pubescence. Medium number of subcutaneous dots, brown color. No stripes. Dense waxy coating. Fruit apex rounded, slightly depressed, base rounded, cavity medium depth. Equatorial suture weakly expressed, does not crack. Skin thin, dense, easily removed, loose texture. Flesh color yellow, slightly darkens in air. Pulp cavity single-colored with flesh. Flesh texture fine-fibrous, dense, juicy. Peduncle medium length — 14 mm, medium thickness — 1.8 mm. Pit round, 18 mm long, 16 mm wide, 10 mm thick, medium size, weight 1.4 g, 3.9% of fruit flesh weight, light brown color. Apex broadly rounded, base narrowly rounded, dorsal suture medium open. Ventral suture medium. Central rib medium expressed. Lateral ribs weakly noticeable. Ridge small, sharp. Surface finely pitted and bumpy. Pit easily separates from flesh.
Fruits are good for fresh consumption and for making jams, dried fruits, juices and marinades. Preservation quality ratings: frozen fruit — 4.2 points, dried plum — 4.1 points, compote — 4.3 points, juice with pulp — 4 points, marinated fruit — 4.4 points. Fruits contain, per fresh weight: dry matter — 16.2%, sugars — 10.6%, acids — 0.67%, sugar-acid index 15.82, pectin substances — 0.68%, soluble polyphenols — 334 mg/100g, ascorbic acid — 4.8 mg/100g.
Flowering period medium — mid-April. Self-incompatible. Ripening period medium — mid-August. Tree enters fruiting stage on 4-5th year. Winter hardiness medium or above medium. Drought resistance medium. Variety resistant to polystigma, clasterosporiosis, shark, but not resistant to moniliosis. High yield, but not sufficiently regular.
Advantages of variety: high yield, excellent fruit taste.
Disadvantages: strong growth, insufficiently intense fruit color, self-incompatibility.
