NEW PARTHENOCARPIC HYBRID OF CUCUMBER SLAVA F1 FOR PROTECTED GROUND CONDITIONS
In solving the issue of fully meeting the needs of the consumer market, it is of great importance to expand and increase the supply of domestic cucumber crop varieties. That is why today it is relevant to create parthenocarpic hybrids F1 cucumber gherkin type with resistance to major diseases adapted to the conditions of film greenhouses. The aim – on the basis of scientific and methodological justification and selection of stable parent forms to create a parthenocarpic heterotic hybrid F1 cucumber gherkin type female flowering type, with high yield and marketability of fruits, resistant to root rot and peronosporosis is intended for growing in film greenhouses. Methods. Field, laboratory and statistical tests. The study was conducted at the Institute of Vegetable and Melon Growing of National Academy of Sciences in protected ground conditions. Results. As a result of breeding work, a new medium-early hybrid of the Slava F1 cucumber was created with a yield of 24,1 kg/m2, a marketability of 95 %, the fruiting period of which is 54 days, parthenocarpic type (73-85 %), resistant to diseases. The average weight of the fruit is 74 g. the fruit is a short green leaf (8-9 cm), medium in diameter (2,0-3,2 cm). Chemical composition: dry matter content – 7,16 %, total sugar – 2,20 %, vitamin C – 9,47 mg/100 g. tasting rating of fresh fruits – 9,0 points, salty –8,7. Growing a new hybrid provides an economic effect of 66 UAH/m2. Conclusions. The hybrid is recommended for expanding the assortment when growing in protected ground in spring and summer culture in film and glass greenhouses with and without heating for agricultural enterprises of various forms of ownership and management, processing enterprises and the private sector in all zones of Ukraine. The hybrid was submitted for qualification examination to the state service for the protection of rights to plant varieties.
