Abstract

The aim of the experiment was to select high-yielding cucumber (Cucumus sativus L.) hybrids suitable for cultivation in unheated film greenhouses. In unheated film greenhouses, the morphological, biological and economic characteristics of 20 F1 cucumber hybrids were comprehensively evaluated, and it was found that Khan F1 (55 days) was superior in terms of early maturity; the standard fruit diameter for the Orzu F1 hybrid was 3.8 cm, while for all the studied hybrids it was 3.5–3.9 cm; plants were found to be 225 to 265 cm tall with 28 to 35 leaves; the total weight of fruits per plant during the period of technical ripeness of fruits was 4.7 kg in the control Orzu F1 hybrid, and Dayara F1, Sardor F1, Fontina F1 hybrids were 111.1–114.8% higher than the control, or 5.2–5.4 kg; in terms of yield, Fontina F1, Dayara F1 and Sardor F1 hybrids were 16.2–16.7 kg/m² or 111.0–114.8% higher than the standard.
