Data on a new heterotic tomato hybrid F1 Pamyati Kvasnikova are presented. The research was carried out in a film greenhouse of the greenhouse complex of the Poisk company. The starting material for the creation of the new F1 hybrid was mainly mutant lines (gene carriers) of marker traits created earlier in the Department of Breeding and Seed Production at the Institute of Vegetable Growing: Sp+ (self-pruning – indeterminate habitus of the plant), J-2 (jointless – peduncle without articulation), S (self-incompatibility – simple flower inflorescence or bi-bifurcate inflorescence – intermediate (two–branched) inflorescence), O1 – oval (elongated fruits with a small number of chambers resistant to radial cracking). The best hybrid combination, distinguished by a complex of economically useful features, after production evaluation and testing, was transferred to the State Commission under the Pamyati Kvasnikova title. The hybrid passed an expert assessment and in 2023 was included in the State Register. The hybrid is medium-ripened, the growing season from germination to the beginning of fruit ripening is 105–110 days. The plant is indeterminate, the height of the main stem is 180–190 cm. Plum-shaped fruits (index 1.45–1.55), weighing 75–90 g, 2–3 chambers in the fruit, their location is correct, high density, resistant to cracking and shedding, good quality and taste, contain 5.5–6.0% dry matter. The yield of the hybrid is 15.5–17.5 kg/m2, which is higher than the standard level of the F1 Scarlet Caravel hybrid. The ripe fruits of the new F1 hybrid Pamyati Kvasnikova are characterized by high shelf life compared to the standard F1 Alaya Karavella hybrid. The experimental batch of mature fruits of the new hybrid had practically no diseased fruits on the 25–30 day of storage, whereas the standard hybrid had 80–90% of diseased fruits on the 10th day of storage.

Key words: tomato, F1 hybrid, breeding, preservation.
