White-leaf

A summer local widely distributed low-Volga variety, officially approved in the Lower Volga region.

A large tree, moderately growing (height 4.5 m, crown diameter 4.8-5.2 m, crown volume 30.4 m3), with a vertically-oval, moderately dense and leafy crown. Main branches are straight, thick, emerging from the trunk at a 45-degree angle. Bark is brown or light-gray, flaking.

Branches of medium size, straight, light-brown, slightly hairy with a small number of hairs. Buds are large, broad, broad-conical, with weak woolly hairs, slightly deviated.

Leaf blade is equilateral, medium-sized, oval, light-green, smooth, glossy, leathery, moderately hairy on both surfaces. Leaf margins are finely toothed. Petiole is short, strongly hairy, with weak anthocyanin, no transition to the central vein. Stipules are medium-sized, lanceolate.

Flowers in inflorescences up to 10, medium-sized, white. Pedicels are medium length, densely woolly. Sepals are light-green, narrow-angled, medium length, petals medium, round. Stamens 20, filaments white, anthers small, pale-pink, almost white. Pistil positioned at the level of the anthers, densely hairy.

Fruits are slightly smaller than average, weighing 60-110 g, short-pome shaped, slightly ribbed, dry to the touch. On the main light-yellow background, there may be a small, blurred pale-pink blush covering 1/5 of the fruit surface. Lenticels are of medium quantity, small, green, weakly visible, without halo. Peduncle is medium, thin, curved, woody, oblique, without swelling, bare, light-brown. Ostiole is small, narrow, without swelling or rust. Calyx is open, medium-sized. Sepals are separate, medium-sized, acute. Receptacle is deep, weakly ribbed, without pearls. Subcalyx tube is cup-shaped, narrow and small. Ovule is bulbous, medium, located in the center of the fruit or occasionally closer to the apex, axial, symmetrical. Seed chambers are closed, bud-shaped, walls smooth. Seeds are acute-oval, dark-brown.

Fruit flesh is white or cream-white, finely granular, with a medium amount of small stone cells, dry, sour-sweet, slightly astringent taste, with weak aroma. Chemical composition of fruits: dry matter — 15.5% (15.4-15.6%), total sugars — 8.4% (8.2-8.5%), titratable acids — 0.29% (0.25-0.33%) on fresh weight, ascorbic acid — 5.5 (7.1%) mg/100g, total pectin substances — 1.73% on fresh weight.

Harvesting period — end of August, fruits can be stored no more than 10 days. This is a table variety. Technological rating of compote — 4.2 points, jam — 4.7 points. Seeds can be used for growing pear rootstocks.

Trees begin fruiting on the 5-6th year after planting. Average yield is 32.5 kg per tree.

Based on field evaluation, drought, heat, and cold resistance are high. The variety is highly resistant to fungal and bacterial diseases.

Advantages of the variety: high disease, pest, and environmental resistance, high technological rating for compotes.

Disadvantages of the variety: vigorous tree growth, average appearance and taste of fruits.
