It was shown that the introduction of the proline dehydrogenase suppressor gene into the Zymoyarka variety wheat genome increased the drought tolerance of leaves photosynthetic apparatus. Biotechnological plants, obtained by regeneration from calluses, selected on a selective medium with mannitol, had advantages by flag leaves gas exchange parameters of over the initial variety, both under normal conditions and under soil drought. Plants of transgenic and biotechnological lines of wheat were characterized by higher intensity of photorespiration and activity of chloroplasts antioxidant enzymes SOD and APO, which contributed to the better flow (run?) of adaptation processes and resulted in the preservation of greater efficiency of light energy use in photochemical processes under drought condition. The grain productivity of transgenic plants was 8%, and in plants of the biotechnological line by 14% higher than the original variety during the effects of drought, it was established.
