Summary The article uses the results of field experience conducted in the seed production department of the Omsk NPP in 2022, on the comparative test of medium-ripe varieties of soft spring wheat. The best varieties in terms of the efficiency of using air humidification deficiency during the peeling-wax ripening period (grain formation and filling) in the formation of grain yield during their placement, both in pure steam and in grain precursor - Lutescens 205/12-5, Baisan, PIC Aquilon, Omsk Fortress, Gonets and Lutescens 242/13-10.

Keywords: soft spring wheat, variety, precursor, air pressure deficit (VPD), grain yield, efficiency.
