The article is devoted to the study of several tomatoes introduced and created in Vegetable Growing Research Institute (Baku) and pure lines derived from them. Biological and economically-valuable characteristics of varieties and obtained pure are given. It should be noted that in Azerbaijan, 25 different varieties of tomatoes are introduced and localized. These varieties have been cultivated on farms for years and have lost their farm valuable qualities due to various biotic an abiotic factors. Although tomato is a self-pollinating plant, special selection and seeding measures are required for reproduction. Therefore, in order to restore the original characteristics of regionalized tomato varieties, it is necessary to re-study their biological characteristics and economically-valuable qualities. Our research was carried out in the direction of individual selection and acquisition of pure lines of typical plants with characteristic features and characteristics. In the course of the work, 2–3 best pure lines were separated from each variety. These lines differ from the parent varieties in terms of ripening time, fruit weight and productivity. Thus, as a result of experiments, it was determined that they give the product in 10–15 days, the characteristics of coexistence are also high, forming uniformity in shape, size and color. The obtained lines are promising, will be included in the selection of seed work as a valuable starting material, and will also be increased.
