Martyanovskoe (Sayanskoe)

Autumn variety developed at the Minusinsk Experimental Station for Horticulture and Vegetable Growing by pollinating the Lalitino variety with pollen mixtures of large-fruited varieties Borovinka, Bessemianka Michurinskaya, and Belfler-Chinese in 1956. Authors: V. A. Shevchenko, V. I. Shevchenko, G. A. Muraviev. Included in the State Register of Selection Achievements approved for use in the Eastern Siberian region since 2000. Distributed in southern areas of Krasnoyarsk Krai and the Republic of Khakassia.

Medium-sized tree, height 2.9 m, medium-growing. Medium-density, round crown. Branches straight, compactly arranged, branching off the trunk at nearly a right angle, branch tips directed upward. Bark on the trunk and main branches smooth, greenish. Predominant fruiting forms — rings, spear-like structures, and fruiting twigs.

Medium-sized, straight, round-sectioned, brown shoots with slight pubescence. Small number of buds, medium size. Buds pressed, medium size, round, smooth. Leaves medium-sized, egg-shaped, dark green, glossy. Leaf blade slightly concave, curved upward, no pubescence. Leaf margin serrated-toothed. Petiole medium length and thickness, slightly pubescent. Stipules large, elongated.

Flowers medium-sized, deep-cup-shaped, pink, fragrant. Petals oval, stamens short. Style medium, weakly pubescent, stigma level with stamens.

Fruits average weight 32 g, maximum 48 g, one-dimensional. Shape round, surface slightly ribbed. Skin delicate, smooth, glossy. Color at consumer maturity: main — greenish-yellow, covering — mostly fruit surface, moderately expressed, blurred, dark red. Under-skin spots — small quantity, medium size, gray, clearly visible. External appearance attractiveness — 4.7 points. Peduncle long, medium thickness, straight. Calyx deep, acute-conical, medium, no rusting. Calyx not falling, closed. Receptacle small, wide, smooth. Heart large, bulbous. Chambers open, medium. Subcalyx tube long, medium width, sac-like. Seeds medium, round, light-brown.

Flesh greenish, medium density, fine-grained, very juicy. Taste character sour-sweet, with spice, medium aroma, tasting score 4.4 points. Fruits contain: dry matter — 11.6%, ascorbic acid — 12.3 mg/100g, sugars — 13.4%, titratable acids — 0.79%.

Autumn ripening variety — first half of September. High fruit marketability, good transportability, fruits keep well for up to three months in storage. Universal purpose variety.

Self-sterile, best pollinators — Minusinsk Red, Tubinskoe. Early-bearing, enters fruiting on 3-4 years after planting (4-5 years after budding year in nursery). Productivity increases moderately but steadily. Average yield of 10-year-old trees — 90 centners/ha, or 13.8 kg/tree, maximum — 142.2 centners/ha. Fruit-bearing periodicity moderately expressed. Fruits do not drop.

Propagation methods — budding and spring grafting by cutting, rootstock — seedlings of Purpurovaya Ranetka. Recommended planting scheme 5 x 3-2.5 m. Variety responds well to fertilization and irrigation. Crown forms freely-growing, trunked, with one or two tiers of main structural branches.

High winter hardiness (in 1980, at -42.8°C air temperature, overall freezing degree up to 2 points). Drought-resistant, high heat tolerance. Resistant to scab (leaf damage degree not more than 0.3 points, fruit damage — 0.2 points). Flowers tolerate light spring frosts.

Advantages of the variety: high winter hardiness, early fruiting, scab resistance, high consumer fruit quality, fruit drop resistance.

Disadvantages of the variety: in some years fruits may be bitter.
