ECOLOGICAL AND GENETIC VARIABILITY OF PIGMENT CONTENT IN THE LEAVES OF SOYBEAN VARIETIES OF THE NORTHERN ECOTYPE
In 2016-2018 years with contrasting weather conditions on 7 varieties and 2 lines of soya developed by VNIIZBK the influence of meteorological conditions on the content and ratio of photosynthetic pigments in the leaves was studied in connection with resistance to the conditions of the Central Black Earth region of the Russian Federation. At the average for 3 years maximal content of chlorophyll a was observed for varieties Mezenka, Svapa, Shatilovskaya 17 (7,16-7,39 mg/g of dry substance); chlorophyll b - for Zusha, Mezenka, Svapa (4,63-4,65 mg/g of dry substance); carotenoids -for Shatilovskaya 17, Svapa, Krasivaya Mecha (1,77-2,24 mg/g of dry In 2016-2018 years with contrasting weather conditions on 7 varieties and 2 lines of soya developed by VNIIZBK the influence of meteorological conditions on the content and ratio of photosynthetic pigments in the leaves was studied in connection with resistance to the conditions of the Central Black Earth region of the Russian Federation.
