A scale for assessing the resistance of samples was developed, which is based on determining the change in the content of total chlorophyll in leaves after exposure to ozone. The best genotypes were evaluated and identified by the indicator of the decrease in the content of total chlorophyll in the leaves of vegetable plant seedlings (resistance to ozone): tomato - L 322 F8 (4 points); sweet pepper - L 118 (NP-4 F5) (7 points); eggplant - L 152 (Nasoloda F5) (9 points). According to productivity, samples of tomato L 322 F8, sweet pepper – L 126, eggplant – L 152 were selected. According to the content of dry soluble matter, samples of tomato L 322 F8, sweet pepper – L 120, eggplant – L 152 were selected. Models of varieties of edible tomato, sweet pepper, eggplant were developed. Product Description popup.authors Volodymyr I. Knysh Romanenko Petro Vasyl V. Kokoiko Oleksandr S.
