Methods. Field, laboratory, statistical. The research was conducted at the Institute of Vegetable and Melon NAAS in a protected soil. Results. According to the results of research, it was found that the studied hybrid combinations F1 are classified as medium-early (47–50 days) and medium-ripe (51 days). High variability of the duration of the fruiting period was noted, which averaged from 52 to 58 days (СV = 26,80 %). The highest total and marketable yields were characterized by hybrids F1: Anus / № 11 (24,5 kg/m2 and 23,1 kg/m2) and Kuzya / LD (25,5 kg/m2 and 23,8 kg/m2), which significantly exceeded the standard Krispina (St1) and Nadiya (St2) (SSD05 (2019-2020 yy.) = 1,27–1,68 and 1,01–1,36). The studied hybrids had a high marketability of products from 92 ± 4,9 % in a hybrid Nadiya F1 (St2) to 95 % in a hybrid F1 Anus / № 11 with a variation range of 3,0 %. Analysis of the biochemical composition of cucumber fruit showed that the dry matter content of 3,90–8,50 %, total sugar 2,20–2,87 % and vitamin C – 6,25–11,61 mg/100 g. Conclusions. As a result of testing new hybrid combinations of the first generation cucumber in the conditions of protected soil, the best hybrids F1 were identified: Anus / № 11 and Kuza / LD for the total (24,5–25,5 kg/m2), commodity (23,1–23,8 kg/m2) yield, marketability (95–94 %), productivity (7,5–8,4 kg/plant), quality indicators of fruits and their stable manifestation. These genotypes are recommended for use in further breeding work and involvement in breeding programs to create early-maturing, high-yielding with high quality and taste competitive parthenocarpic hybrids F1 of gherkin-type cucumber.
