Kishmish White Oval grape (Vitis) – an ancient seedless grape variety of medium ripening period. Presumably native to Central Asia and the Near East. It is a bud mutation of a seeded grape variety of the eastern ecogeographical group.

Vines are vigorous. Shoot ripening is good. Leaves are medium-sized, rounded, three- or five-lobed, with margins turned upwards, glabrous. Flower is hermaphroditic.

Bunches are medium, cylindro-conical, winged, of medium density, average weight 180–230 g. Berries are small, oval, yellowish-green or amber-yellow. Skin thin, translucent, with small black dots. Flesh is fleshy, pleasant in taste. Seeds are completely absent or underdeveloped. Sugar content up to 22–30%. Acidity 6 g/l. Period from budbreak to full berry ripening 160–170 days with a sum of active temperatures of 3200°C. Yield 100–150 centners/ha; with a high level of agronomy reaches 200 centners/ha and above.

Frost hardiness zone: 5–8 (-22°C).

Site: Not demanding as to soil, but grows better on light, sufficiently moist, well-warmed and well-drained soil.

Planting and care: Similar to those for cultivated grape. It is recommended to use gibberellin after fruit set to increase berry size and even out berry size.

Pruning: Recommended load is 22–24 shoots (30–35 buds) per feeding area of 4–6 sq. m. Fruiting canes should be pruned to 8–10 buds.

Diseases and pests: Resistance to fungal diseases and pests is weak.

Propagation: Rooting ability of cuttings and compatibility with rootstocks is good.

Usage: From the Kishmish White Oval grape variety are produced bedon, sabzu zolotistaya, soyagu, white raisins, etc.; the grape is also used for fresh consumption.
