Influence of individual elements of hybrid seed technology on seed productivity of the parent form of cucumber F1 Murava

Relevance. It is very important not only to create a hybrid of cucumber, which in all respects suits the producers of vegetable products, but also to ensure that the production of hybrid seeds with high varietal and sowing qualities is not unprofitable. A high yield of hybrid seeds can be obtained only with good pollination of the maternal line, for this purpose there should be enough male flowers on the paternal form and the flowering time of the parent forms should coincide. Materials and methods. The research was carried out in the first turn of the winter greenhouse with low-volume cultivation technology in 2017-2018. The object of research was the parent forms of a promising hybrid of parthenocarpic type F1 Murava. The maternal form is of the female type, the paternal form is predominantly of the female type of flowering. Terms of sowing of parental forms were studied: simultaneously and with a difference of 7-8 days. Experiments on different variants of treatments of the paternal form with gibberellic acid (concentration 0...
