Formation of yield and commodity qualities of potatoes, depending on the varietal characteristics

The article presents data on the study of the effect of varietal characteristics of potatoes on the formation of yield and quality of tubers. The aim of the work was to identify the best varieties of potatoes for cultivation in Nizhny Novgorod region. For conducting research, the following methods were used: experiments at cultivation, storage, use of potatoes, laboratory studies, tasting evaluation, and ranking. The effect of tuber damage by common scab and rhizoctoniosis on the safety of potato tubers was revealed. It had been established that all varieties of potatoes in conditions of highly cultivated sod-podzolic soils form a high yield of tubers. The maximum yield provides cultivation varieties Crystel and Sandrine. Crystel and Sandrine Varieties were characterized by a maximum yield of marketable tubers and weight per tuber. They also had the high starch content in tubers, the maximum tasting and overall assessment of tubers. It was noted that tubers of all varieties were slightly affected by common scab and rhizoctoniosis, which had a positive effect on their ability to work. To a lesser extent, these diseases affected the tubers of the varieties Crystel, Sandrine, and Serafina. The quality of these varieties was at the level of the standard.
