Now low-volume hydroponics as a modern and cost-effective method of cultivation is widely used for the production of vegetable crops. However, it is necessary to have varieties and hybrids adapted to the specific growing conditions. In 2019 year selection work for creating hybrids for hydroponic technology “Fitopiramida” was started. The first stage of the breeding work, which we started in 2019, was the development of a tomato hybrid model for the «Fitopiramida» technology, to clarify the parameters of which in 2019-2020, 4 cherry tomato hybrids (F1 Corallovye busy, F1 Elf, F1 Volshebnaya arfa, F1 Lunny fontan) and 2 cocktail tomato hybrids (F1 Zolotoy potok, F1 Krasny lucum) of indeterminate growth type were tested on multi-tiered vegetation pipe installations. Researches were conducted in 2019-2020 in the polycarbonate unheated greenhouse «Fitopiramida» with partial regulation of microclimate parameters (III light zone). The temperature and relative humidity of the air were regulated by airing, but on hot Sunny days the temperature in the greenhouse rose to 30 °C. Tomato sowing in 2019 was carried out on April 5, and plants were planted on plants on April 29. In 2020, sowing was carried out on April 15, and planting on installations-on may 8. Plants were formed in 1 stalk, up to 3 brushes with the removal of the growth point. Duration of plants in hydroponic installations in 2019 and 2020 it was 99 and 106 days, respectively. Received data on earliness, yield, plant productivity, marketability, blossom-end rot damage allowed to clarify parameters of the hybrid model. For two-year researchers all tomato hybrids grown on hydroponic installations were included in the early ripening group (the period of «germination-beginning of ripening» was 65–79 days). Following the received results tomato hybrids F1 Korallovye busy and F1 Zolotoy potok are considered perspective for hydroponic technology «Fitopiramida».
