Narma is a Dagestani technical grape variety with a medium ripening period, belonging to the Eastern eco-geographical group. Under the conditions of the Derbent district, the period from bud break to full berry maturity is about 133 days with a sum of active temperatures of 2790–2900°С. The bushes are vigorous with good shoot ripening. Leaves are large, rounded or slightly oval, dark green saturated color, five-lobed, net-veined and wrinkled, with down-curved margins and a glabrous underside. Flowers are perfect, which contributes to stable fruiting.
Clusters of Narma are medium-sized, predominantly conical in shape, sometimes cylindro-conical, with a wing, loose or medium-density. Berries are large, round, pale green or white-green tinted, covered with a weak waxy bloom. Skin is thin, and pulp is juicy and melting, giving the grape a pleasant taste and making it suitable for various types of processing. The yield of the variety is 100–140 centners per hectare.
The Narma variety has low disease resistance: it is inferior to European varieties in resistance to downy mildew, is heavily affected by powdery mildew, and is damaged by the grape leafroller. Despite this, the grape is widely used for the production of white ordinary table wines and grape juice, and is also suitable for home canning. Thanks to its technical characteristics and taste qualities, Narma is a valuable variety for winemaking and processing in the region.
