RESULTS OF ENVIRONMENTAL TEST OF PILOT BLACK CURRANT VARIETY

Abstract

The purpose of the study is replenishment of the assortment of black currant for the Volga-Vyatka region. The blackcurrant variety Pilot was bred in the conditions of the Middle Urals, at Sverdlovsk horticultural breeding station. It was obtained from free pollination of Valovaya variety. Pilot variety was tested in five regions of the Russian Federation - in the system of state variety testing and in various scientific and educational institutions under scientific cooperation agreements. The studies were carried out according to the "Program and Methodology for the Study of Fruit, Berry and Nut Crops" (Oryol, 1999). In 2021, Pilot variety deservedly replenished the assortment of black currant for cultivation in the Volga-Vyatka (4) region,it is also suitable for cultivation in other regions of the Russian Federation. Pilot variety can serve as a starting material for further improvement of the blackcurrant assortment.
