Harbovska, Tetiana
An evaluation of promising hybrid combinations of cucumber (Cucumis sativus) was carried out according to breading characteristics. It was established that the investigated F1 hybrid combinations belong to the group of medium-early (47–50 days) and medium-ripening (51 day). A high variability of the length of the fruiting period – from 52 to 58 days (s%= 26.80 %) – was noted. The F1 hybrids Anus/No. 11 (24.5 kg mE−2 and 23.1 kg mE−2) and Kuzya/LD (25.5 kg mE−2 and 23.8 kg mE−2) were characterized by the highest total and marketable yields, which significantly exceeded the standard of Crispin (St1) and Nadiya (St2) (p is less than 0.05). The investigated hybrids had a high marketability of products: from 92% in the hybrid Nadiya F1 (St2) to 95% in the hybrid F1 Anus/No. 11. The analysis of the chemical composition of cucumber fruits showed that the content of dry matter was 3.90–8.50%, sugar – 2.20–2.87%, and vitamin C – 6.25–11.61 mg 100 gE−1. The testing of the new hybrid combinations of first-generation cucumbers under protected area conditions demonstrated that according to the values of the general (24.5–25.5 kg mE−2) and marketable (23.1–23.8 kg mE−2) productivity, marketability (95–94%), and the qualitative indicators of fruits and their stability, the best F1 hybrids were Anus/No. 11 and Kuzya/LD.
