This article presents the results of the three-year data analysis of DUS testing of the spring wheat (Triticum aestivum L.) collection by morphological varietal characteristics. The following cultivars were identified as candidates for example varieties: Ivolga, Iren’, Lisa, Talba, Chelyaba rannaya, Bazhenka, Grechanka, Dal’gau 3, KWS Shirokko, Silantiy, Start 1, KWS Torridon. These varieties reflect all the gradations of found characteristics. Among them, varieties with unique states of expression of characteristics were identified: Iren’ (strong anthocyanin coloration of the flag leaf auricles), Talba (very strong anthocyanin coloration of the flag leaf auricles), KWS Shirokko (weak glaucosity on the flag leaf sheath, very weak glaucosity on the flag leaf back), Dal’gau 3 (very weak glaucosity on the ear). No varieties were found with the following states of expression of characteristics: bush type – semi prostrate (7), prostrate (9); anthocyanin coloration of the flag leaf auricles is medium (5); glaucosity on the flag leaf sheath is absent or very weak (1); glaucosity of the neck is absent or very weak (1), weak (3).
