Abstract

The purpose of the work is to create new domestic tomato hybrids for protected soil with high adaptability and an increased content of biologically active compounds for functional nutrition. 9 new tomato hybrids were evaluated in the control nursery of the preliminary test on the basis of Teplichnoye JSC in conditions of low-volume hydroponics without additional illumination. The hybrids G-1214-23, G-922-23, G-122-23, F1 Nastavnik had the highest productivity, providing yields above 50 kg/m2 in extended turnover. An extended biochemical analysis of the fruits of nine of the most promising tomato hybrids with more than 36 indicators was carried out. For further testing, registration and entry into the State Register of Breeding Achievements, a sample with a high content of biologically active compounds and high productivity G-922-23 and highly productive samples G-1214-23 and G-122-23 are recommended as a tomato hybrid for functional nutrition.
