The article provides the results of testing 13 soft spring wheat variety samples of the Federal State Budgetary Scientific Institution "Omsk ASC" in the competitive variety testing nursery in 2020–2022. According to the ripeness groups, characteristics is given according to phenotypic traits, resistance to leaf diseases and grain quality. Variety samples have been identified based on yield, stability factor (S.F.) and yield range (d), with weaker variability (CV), which exceed standards and are characterized by the highest level of realization of productivity potential. In medium-ripeness group the following variety samples have been selected: Lutescens 83/14-3, Lutescens 205/12-5, in mid-late maturity group – Lutescens 15/16-17, which ensure the formation of a consistently high grain yield, grain quality, and resistance to fungal pathogens, regardless of the environmental conditions. The parameters of ecological plasticity of variety samples according to grain yield were determined and the most adaptive ones in this set were identified – Lutescens 83/14-3 (b i =1.16, S d 2 = 0.02) and Lutescens 205/12-5 (b i = 1.09, S d 2 = 0.03). The obtained research results made it possible to transfer the cultivars ‘Omskaya krepost` 2’ (Lutescens 205/12-5) and ‘Omskaya krepost` 5’ (Lutescens 83/14-3) to the state variety testing. Using the PCR method, a genetic profile of the transferred cultivars was obtained using certain DNA markers.
