Creation of competitive varieties of melon and pumpkin with valuable economic trends

Abstract

Relevance. The soil and climatic conditions of the Lower Trans-Volga region are considered favorable for melon growing and make it possible to obtain high-quality products. The purpose of the research was to create new competitive varieties and hybrids of melon and pumpkin.Materials and methods. The object of the research is new varieties of melon and butternut pumpkin created at the Bykovskaya melon breeding experimental station. Melon cultivar Osen and pumpkin cv. Zhemchuzhina were used as standards. The methods of creation are intervarietal hybridization, individual and mass selection. During the growing season, appropriate observations and counts were carried out.Results. As a result of many years of breeding work at the Bykovskaya cucurbits selection experimental station, a melon cultivar 251 and a pumpkin cultivar 509 have been created. both producers and consumers. Therefore, the obtained varieties were evaluated for taste, yield, resistance to biological and abiofactors of the environment, dry matter content, fruit size, fruit and pulp color. During the comparative assessment of the accessions, it was determined that the new varieties of melon and pumpkin exceed the standards in terms of the main economically valuable traits. The average yield during the study, in the melon cultivar 251, exceeded the standard by 47.8%. In the pumpkin cultivar, the average yield for three years of research exceeded the standard by 69.6%. In terms of taste, the new melon variety was at the level of the standard, the cv. Osen. A variety of butternut pumpkin exceeded the standard in all quality indicators. The susceptibility to powdery mildew in the melon cultivar varied depending on the year of research. The melon sample showed resistance to anthracnose higher than the standard by 16.4 and 18.6%, over the years of study. In the pumpkin cultivar, resistance to powdery mildew and anthracnose was higher than the standard, on average by 34.9% to powdery mildew and by 28.6% to anthracnose. Thus, new varieties of melon and pumpkin meet the modern requirements of the industrial melon industry, are resistant to environmental stress factors, common diseases, and have economically valuable traits.
