| Abstract | Objective. This study presents the results of agrobiological research on large-fruited pumpkin varieties conducted in the lowland zone of Transcarpathia during the 2023–2024 growing season. Methods. Through phenological observations, biometric analysis, and yield recording, several key findings were established. Results. The domestic variety Titan excelled in germination rates, the timing of male and female flower appearance, and the onset of technical ripeness. The Italian variety Big Max reached biological maturity the fastest, while the Dutch variety Muscat de Provence showed the most rapid formation of lateral shoots and fruits, as well as the shortest overall growing season (120 days). It was observed that Muscat de Provence exhibited the earliest formation of the first female flower (on the 6th node of the main shoot, compared to the 7th and 8th nodes in other varieties) and the highest number of flowers (65 male and 28 female, compared to 62/21 in Titan and 50/26 in Big Max). The largest fruits were produced by the Big Max variety (46.8 × 48.0 cm), with a seed chamber diameter reaching 33.4 cm. While Muscat de Provence had the smallest fruit dimensions (28.2 × 34.7 cm) and seed chamber (10.5 cm), it stood out for its pulp thickness (24.2 cm, compared to 20.1 cm in Titan and 14.6 cm in Big Max). Conclusions. Big Max recorded the highest fruit weight (8.2 kg), seed weight per fruit (112 g), and 1000-seed weight (395 g). Furthermore, Big Max achieved the highest yield per plant (24.6 kg) and the greatest total yield (61.5 t/ha, compared to 56.3 t/ha for Titan and 44.8 t/ha for Muscat de Provence). The highest marketability rate was recorded for the Muscat de Provence variety (99.5%). | ||
