The cucumber variety Surprise 66 F1 is a mid-early hybrid developed by the Transnistrian Research Institute of Agriculture and recommended for cultivation in the Northern, Northwestern, and Central regions of Russia since 1973. The plant is medium-height with cylindrical fruits 14–18 cm long and weighing about 112 g. The fruits are large-scaled, free of bitterness, with crisp, juicy flesh and good flavor, making them an excellent choice for fresh consumption, pickling, and canning. Fruit ripening occurs 55–60 days after sowing, allowing harvest during summer and autumn.
The variety is highly resistant to powdery mildew and downy mildew, and also possesses immunity to several other diseases, significantly simplifying plant care. Additionally, Surprise 66 F1 demonstrates high drought tolerance, cold and heat resistance, making it a reliable choice for various climatic conditions. Market yield reaches 12.9 kg/m², and the fruits withstand transportation well, which is important for commercial cultivation.
For successful cultivation, seeds should be sown into the soil upon the arrival of stable warmth, when nighttime temperatures remain above 12 °C and soil temperature is at least 14–15 °C. To enhance cold resistance, seeds can be pre-chilled in a damp cloth in the refrigerator for two days. Sowing can be done in stages — early and late May, as well as early June — to extend the fruiting period and ensure a continuous supply of fresh cucumbers.
