This variety was created at the M.A. Lisavenko Institute of Fruit Tree Breeding in the mountainous Altai region (Chamal) by crossing the Okya variety with the Ussuri cherry plum variety 'Chamal Yellow' in 1953. Authors: V.S. Putov, I.A. Puchkin, T.M. Pleknev. Included in the State Register in 1991 for the East Siberian region.
Trees are medium-sized with a moderately open, flat-rounded, slightly drooping crown. The main type of fruiting is in cluster branches. Branches are gray-brown, smooth, emerging from the main scaffold branches at an obtuse angle. The trunk is low. Shoots are straight, brown-olive in color, reddish at the top, bare, with few buds. Vegetative buds are conical; fruit buds are round. Leaves are of medium size, green. Leaf blade has a wedge-shaped base, slightly concave, folded like a boat, gradually tapering to a sharp tip, glabrous, with doubly serrated edges, hanging. Petiole is of medium length, pigmented. Each bud contains 3 flowers, which open before the leaves. Flowers are rose-like, white.
Fruits are round, 30 mm high and 33 mm in diameter, average weight 10-12 g, with a deep depression and a barely noticeable seam. Main color is orange, covered with a light-red blush. Skin has dark-red basal spots and a weak waxy coating, smooth. Flesh is greenish-yellow, fairly firm, juicy, pleasantly sour-sweet. Stone is medium-sized, oval-rounded, well-formed, detaching and semi-detaching from the flesh, smooth. Peduncle is short, easily separates from branches.
Fruits ripen in the second half of August. They contain 16-22% soluble solids, 8.3-14.3% sugars, 1.4-1.6% titratable acids, 8-12 mg/100g ascorbic acid, and 270-285 mg/100g P-active substances. Fruit transportability is satisfactory. Variety is of universal use.
Begins fruiting on the 3rd-4th year after planting in orchards as one-year-old seedlings. Yield is relatively high, fruiting is irregular. Winter hardiness of trees is high, fruit buds are satisfactory. Not resistant to rot. Affected slightly by Clasterosporium and fruit moth, and significantly by Maslov's seed-eater. Variety is self-sterile.
