Late-autumn variety developed by S. P. Kedrin at the Samara Experimental Station for Horticulture through hybridization in 1936 between Borovinka obyknovennaya and Wagner prizovoy. It has gained wide cultivation in central regions of Russia. Included in the State Register of Selection Achievements approved for use in the Central, Central-Chernozem, North Caucasus, Middle Volga, and Lower Volga regions, and as a standard cultivar — for the East Siberian region.
Trees are fast-growing. Tree crown shape during fruiting is high-rounded or broad-pyramidal. Crown is not dense, allowing light to penetrate to the center. Multi-year branches are brown. Bud-forming ability is below average, but bud break is high. Fruit forms early in the tree's life on young collar buds and twigs. In nurseries, two-year-old saplings are tall, well-developed, and grow excellently on Anise seedlings, Zigulovskaya forest apple, and large-fruited Chinese apples.
Shoots are raised, thick, straight, slightly hairy, dark-brown. Leaves are large, intensely green, elongated-oval in shape with curled tips. Leaf blade has serrated edges, folded like a boat.
Flowers are large. Due to early flowering, in some years the first flowers are damaged by late spring frosts.
Fruits are large, averaging 120-200 g (up to 350 g), one-seeded. Fruit shape is flat-round or round, sometimes with broad ridges. Fruit surface is often slightly rough, sometimes with rust-colored bumps resembling warts. Fruit skin is glossy, tough, and oily. Main color is yellowish, with a covering color of intense red-striped, diffuse blush, sometimes covering almost the entire fruit. Subdermal spots are whitish, numerous, medium-sized, and barely noticeable.
Fruits are very attractive. Fruit stalks are long or medium-length, fairly thick. Calyx is deep and wide, sometimes with slight corking of the skin, not exceeding its boundaries. Calyx is medium to large, open or semi-open. Plate is deep with steep, sometimes ribbed walls. Subcalyx tube is funnel-shaped. Seed cavity is onion-shaped, located in the center of the fruit, with closed seed chambers.
Flesh is creamy, coarse-grained, tender, with good sour-sweet flavor.
Late-autumn variety. Fruit ripens simultaneously, in the first decade of September, in hot dry years — at the end of August. Consumption starts from the third decade of September through December, sometimes until January. Consumer shelf life is 70-90 days.
Fruit production begins at 5-6 years of growth of the scion. High-yielding variety. Bears fruit annually in its young age, less periodically in older trees.
Winter hardiness of trees in Samara conditions is average. The variety is resistant to scab, but is moderately affected by the second generation of codling moth.
Advantages of the variety: early fruiting, high yield, high fruit quality, suitability for cultivation in intensive orchards.
Disadvantages of the variety: average winter hardiness of trees.
