Zaikin, V.V. | Amelin, A.V.
the article presents the results of long-term scientific studies (2010-2016) and the analysis of published experimental data of domestic and foreign scientists on the problem of improving the adaptability of production and the photosynthetic processes of cultural plants by means of breeding. The conclusion is made that plants of modern varieties of buckwheat have a high production, reproduction and photosynthetic capabilities, but low adaptive abilities in extreme weather conditions. As a result of selection activity of biosynthesis of organic substances in plants of buckwheat significantly increased both early and late stages of development, and its stability decreases. The photosynthetic system of plants of buckwheat comments positively on the optimal soil moisture, air temperature and increasing light intensity leaf, but as a result of selection of its resistance to drought has a tendency to decrease, which leads to a significant destabilization of the production process of the variety. For creation of varieties with high and stable productivity 2 identified the source of the high photosynthetic activity and 2 – the stability of production and photosynthetic processes 4 sources to drought and 5 – to cold.
