The results of studies of varieties of spring soft wheat in the conditions of the North-East of Kazakhstan are presented. Sowing was carried out in two ecologically different zones: Pavlodar and Irtysh, according to the predecessors of steam and grain. It was revealed that basically all the varieties studied by us in the conditions of the Pavlodar region belong to the mid-season group. The maximum influence on the variability and the formation of the duration and vegetation period was exerted by the factor “year” - 35.9% on the grain predecessor, and the factor “medium” - 29.0%.
