The morphophysiological parameters of leaves are often used for breeding material screening in selection programs for stress tolerance. In opposite, the pigments content (chlorophyll a and b , carotenoids) and their ratios, stoma quantity and size on both leaf sides and leaf area were involved into characterization of single soft spring wheat variety reactions to different climate conditions at different vegetation stages. Three geographic locations of the Krasnoyarsk Territory were involved. Chlorophyll content along with stoma area appeared to be the most sensitive traits and changed a lot, depending on weather conditions at the certain vegetation stage. So they were considered to be the main predictors of grain yield at 2020 vegetation period.
