Presented are the results of a triennial conjugated study of physiological characters in the course of ontogenetic development of wheat samples (area and surface density of the leaf, chlorophyll content, chloroplasts' activity) as well as protein content in the grain of corresponding specimens defined after their harvest. It is established that protein content in grain correlates negatively (-0,30 - -0,60) with duration of shooting-earing stage and there is a positive correlation - (+0,46 - +0,70) with photoreducing chloroplast activity. A conclusion is drawn that a necessary condition for high protein grain formation is the increased chloroplast activity on reduced producing
