| Popis: | Relevance. The breeding process in identifying new species and flexible capabilities allows the use of genetic sources for the most important economically valuable traits. Market requirements to expand the assortment of cucumber are determined both directly and new approaches to the study of the gene pool and its use. In turn, the domestic market is not always predictable and logical. Thus, the issue of a comprehensive study of the sorting of a gunshot and smooth type of fruit for growing in film unheated greenhouses in order to isolate genetically valuable material for breeding work remains relevant.Materials and methods. The studies were carried out in 2015-2018 on the basis of a pumpkin crop laboratory of the Research Institute of Vegetable Production (NIISOK), of the Gavrish breeding station in Moscow, Krymsk (Krasnodar Territory), the Gavrish Jordanian Experimental Station. Research material – 34 different types of origin from the NIISOK collection. The work used both traditional methods of assessment and modern methods of molecular marking. The purpose of the work is the selection of breeding valuable source material for creating parthenocarpic lines of a cucumber with a smooth type of fruit, a complex of economically significant features, and resistance to disease.Results. The results of variety testing of 20 hybrids of foreign selection on the territory of the Krasnodar Territory (Krymsk) and Jordan are presented. A comparative assessment was made of the inter-varietal and ecological variability of productivity and yield of the studied samples of cucumber culture. Based on the results of studying the modern assortment of hybrids in different regions (Krymsk, Jordan), the optimal parameters of the parthenocarpic hybrid model of a cucumber with a smooth type of fruit adapted to specific growing conditions are determined. |
