Variety Kniaz Trubetskyi

Kniaz Trubetskyi (Prince Trubetskoy) is a hybrid form of private breeding by O. M. Shchennikov (Ukraine). It ripens early-to-mid: in the third ten days of August, about 120–125 days after bud break. The cluster is cylindrical-conical, less often conical, often elongated, loose, from 700 g. The berries are oval, from red-violet to dark violet, with a waxy bloom, with crisp flesh, a skin of medium thickness and a harmonious taste with a pleasant balance of sweet and sour.

The bush is vigorous, the flower is hermaphroditic, the vine ripens well, and yields are high. Resistance to fungal diseases is medium (the variety is still being studied). It withstands frost down to about −22 °C, and the vine is covered for winter. Harvested berries keep for several weeks at about 0 °C.
