Tiered Vegetation Pipe Plant (TVPP) “Fitopiramida” is one of the advanced technologies for growing vegetable crops, which allows to significantly increase the yield of tomatoes per unit area. One of the unique opportunities provided by “Fitopiramida” technology is to obtain a large harvest of tomatoes in a short time both due to earlier ripening and high planting density on installations. For this reason breeding of highly productive and competitive tomato hybrids with group resistance to diseases, suitable for morpho-biological features for cultivation using this technology is actual task. In 2019–2021 the authors developed breeding models of cherry and cocktail tomato hybrids, large-fruited and brush tomato hybrids for “Fitopiramida” technology were developed, in which the specific requirements for tomato hybrids are taken into account. Based on the developed models, methods of material evaluation and selection for breeding work were chosen. To confirm the hypothesis about the possibility of carrying out part of the selections in the conditions of the ground greenhouses technology during breeding for “Fitopiramida”, in 2021 21 indeterminate tomato hybrids F1 (large-fruited, brush, cherry) were tested in the film ground greenhouse of the Selection Center ARRIVG – branch of FSBSI FSVC and in the polycarbonate greenhouse “Fitopiramida” with following correlation analysis of data. Based on the research results, it was concluded that it is possible to evaluate indeterminate tomato hybrids in conditions of film ground greenhouses during breeding for “Fitopiramida” technology by individual characteristics: large-fruited and brush hybrids – by the average weight of one fruit (r = 0.72) and the duration of the period “germination – beginning of ripening” (r = 0.64), cherry hybrids – by yield (r = 0.75) and average weight of one fruit (r = 0.95). For the most reliable assessment and accurate selection of the most promising tomato hybrids, their testing on hydroponic installations is required.
