‘NADEZHDA’ IS A NEW VARIETY OF SOFT WINTER WHEAT ADAPTED TO THE CONDITIONS OF THE MIDDLE POVOLZHIE

Abstract

Due to the creation and introduction of the varieties adapted to the conditions of the Republic of Tatarstan, the areas of winter wheat cultivation increased from 59.300 ha to 339.700 ha during the last 15 years. The staff of the institute developed such winter wheat varieties as ‘Kazanskaya 285’, ‘Kazanskaya 560’ and ‘Nadezhda’ with the stronger adaptive characteristics and a sustained grain quality. The article describes a new soft winter wheat variety ‘Nadezhda’. The variety was created with the method of intraspecific hybridization with the following selection from the hybrids: ‘Mironovskaya 808’/’Meshinskaya 2’/’Kazanskaya 285’. The variety is Lyutestsens, a middle maturing cultivar. The average productivity of the variety during the years of study was 3.5 t/ha. the cultivar showed the productivity increase of 0.5 t/ha compared with the standard variety ’Kazanskaya 285’. The distinctive feature of the variety is the synchronization of the stem formation, which weakens the competition among the first and following stems. The variety ‘Nadezhda’ possesses a powerful autumn tillering that allows sowing it with the norm of 4.5-5.0 ml of germinating seeds per hectare. The cultivar possesses resistance to snow mould, fusariosis and tolerance to drought. It’s valuable wheat with large and uniform kernels. The variety has been approved to use in the Middle-Volzhsky region of the Russian Federation.
