This variety was developed at the NIISS named after M.A. Lisavенко in the mountainous zone of the Altai (Chemal village) by selecting seedlings from open pollination of Ulmus ussuriensis. Authors: V.S. Putov, T.M. Pletneva (Tsypetsavver). It is widely grown in gardens of the Altai region. Included in the State Register in 1965 for the West Siberian region.
Trees are low-growing with a flat-round, non-dense crown. Branches are gray, emerging from skeletal branches at an obtuse angle. The trunk is low. Shoots are straight, reddish-brown. Vegetative buds are conical, fruiting buds are rounded. Leaves are medium-sized, egg-shaped, with a long, curved tip, dark green, smooth, matte, with a smooth margin and fine serrated edges. The leaf blade is nearly flat, hairless, with a short, reddish petiole. Two to three flowers are located in the bud. Flowers are small, white, cup-shaped, blooming before the leaves.
Fruits are small (10-15 g), oval, with a narrow, deep, oval depression divided by a groove and a well-defined ventral seam, evenly arranged. Main color is pale yellow, covered with a weak golden blush and a whitish waxy coating. No skin spots. The peduncle is short, easily separates from the branches, and ripe fruits easily fall off. Skin has barely noticeable bitterness. Flesh is light-yellow, tender, very juicy, loose, sweet, slightly acidic, with good flavor. Pit is medium-sized, oval, smooth, with two grooves, well-formed, easily separates from the flesh.
Fruits ripen in mid-August. Once removed from the tree, they quickly lose market appearance, developing brown spots. Not suitable for storage or transportation. They contain 16-19% soluble solids, 7.3-14% sugars, 1.5-1.7% titratable acids, 0.37-0.51% tannins, 6-12 mg/100g ascorbic acid, and 235-327 mg/100g P-active substances. Variety is of universal use.
Enters fruiting on the 3rd-4th year after planting as one-year seedlings. Winter hardiness of the tree is satisfactory, fruit buds are above average. Yield is high, irregular. Affected moderately by Clasterosporium and fruit moth, significantly by Maslov's seed-eater. Susceptible to rot. Self-sterile.
In selection terms, it is unlikely to be of interest, as among its numerous offspring, no plants have been identified that surpass the mother variety in fruit size or taste qualities.
