Study of varieties and promising varieties of table watermelon in the conditions of the Volgograd Volga region

Abstract

Relevance. Selection and analysis of the source material for crossing varieties with an individual ability to transmit economically valuable traits to offspring is an important breeding task. Breeders conducted research aimed at obtaining highly productive varieties and hybrids of table watermelon of various ripeness groups, resistant to adverse environmental conditions and having high taste qualities in comparison with standards. When studying the varieties and varietals of table watermelon, samples were selected according to the following characteristics: the growing season, yield, bright color of the pulp, excellent taste, dry matter content.Materials and methods. Scientific research was carried out in 2019-2020 in the breeding nursery and breeding nursery in the fields of the Bykovskaya melon breeding experimental station located in the Bykovsky district of the Volgograd region. 2 varieties of Malachite, Timosha and 3 cultivars 697, 728, 750 having an advantage in valuable economic characteristics over the best zoned varieties in the middle–ripening group – Sinchevsky, and in the late-ripening group – Kholodok were studied.Results. Studies have shown that in the middle–ripening group, the new Timosha variety is the most productive (27.3 t/ha), and the variety also stood out with a high dry matter content (13.4 - 14.8%). In the late-maturing group, a variety of 750 (27.5 t/ha) was distinguished by yield. Indicators of dry matter, the percentage of dry matter higher in the cultivar 728 ranged from 13.8 to 14.8%, The tests proved the relevance of further study in the breeding nursery of selected cultivars isolated by a complex of economically valuable traits to create new promising varieties of watermelon. Work in this direction will contribute to an increase in the volume and quality of manufactured products, contribute to the further development of the melon industry.
