Abstract
Relevance. Breeding for resistance to diseases is one of the current trends in melon growing. The work of the Bykovskaya melon selection experimental station includes breeding pumpkin varieties that are not inferior to zoned varieties in terms of economically valuable traits, disease resistance and taste.
Materials and methods. The object of the study was hybrid combinations of large-fruited pumpkin and nutmeg pumpkin, obtained as a result of intervarietal hybridization. The research was carried out in the Bykovsky district of the Volgograd region.
Results As a result of the work carried out, the characteristics of the obtained hybrid combinations of pumpkin were given according to the main economically valuable traits: the duration of the growing season, the average weight of the fruit, the thickness of the pulp, the dry matter content, the yield, as well as the resistance to anthracnose and powdery mildew. An assessment was made in comparison with the standards and parental forms. As a result of the research, it was revealed that the shortest duration of the growing season, 115-117 days, is in combinations of large-fruited pumpkin Paradise - Vi x Graceful, Graceful x Paradise - Vi, Marina di Ch x Dawn. Among the nutmeg pumpkin, all samples along the length of the growing season are at the same level of 119-120 days. Average fruit weight and pulp thickness are inherited intermediately. In terms of yield, among the hybrid combinations of large-fruited pumpkin, samples of Marina di Chioggia x Zorka and Paradise - Vi x Graceful stood out. All hybrid combinations of nutmeg pumpkin exceeded parental forms in terms of yield, their yield ranged from 17.0 to 22.0 t/ha. In terms of resistance to powdery mildew and anthracnose, the combinations "Elia x Spaniard" (Uzbekistan) and "Muscat Provence x Vitamin" stood out.
Conclusions. Thus, as a result of hybridization, two new hybrid combinations of large-fruited pumpkin and Muscat pumpkin were obtained, which have a complex of economically valuable traits and resistance to powdery mildew and anthracnose.
