The article presents the experimental data on the assessment of economically useful traits of eleven new parthenocarpic heterotic cucumber hybrids under the conditions of the spring-summer turnover of the Kirov region. The problem of cultivation of thermophilic crops, which arises in the northern regions of the country, is one of the stages of breeding research. The cultivation of cucumber in the Kirov region is aggravated by unfavorable climatic conditions of the second light zone (short duration of the growing season, low positive temperatures, frosts in the third decade of July and in the first decade of August). The purpose of the scientific work is to evaluate and identify promising parthenocarpic heterotic hybrids of cucumber for growing in unheated greenhouses in the spring-summer turnover of the second light zone. The research was carried out in the laboratory of northern vegetable growing of the Kirov region at the All-Russian Research Institute of Vegetable Growing - a branch of the Federal State Budgetary Scientific Institution Federal Scientific Vegetable Centre in the conditions of polycarbonate unheated ground greenhouses during 2018-2019. As a result of phenological observations and assessment of biometric indicators, the early maturity, early maturity and marketability of the tested parthenocarpic heterotic cucumber hybrids of the selection of Agroholding Poisk and ARRIVG – a branch of the Federal Scientific Vegetable Centre were determined: F1 Avoska, F1 Atos, F1 Buket dlya mamy, F1 Multifrut, F1 Novator, F1 Piligrim, F1 Sprinter, F1 Revansh, F1 Tonus, F1 Express in comparison with the zoned hybrid of cucumber F1 Carolina. A strong negative influence of climatic conditions of the second light zone on the duration of the seedling-fruiting period was determined, which on average over the years of research, depending on the hybrid, varied from 47 to 55 days. It has been established that to obtain early production of cucumber in polycarbonate unheated ground greenhouses of the Kirov region, heterotic parthenocarpic cucumber hybrids F1 Sprinter (3.6 kg/m2), F1 Avoska (2.1 kg/m2) and F1 Atos (2.5 kg/m2). Parthenocarpic cucumber hybrids F1 Sprinter and F1 Atos were noted, which have the highest yield of marketable products, 95.7 and 94.0%, respectively. The most productive parthenocarpic cucumber hybrid F1 Novator (16.1 kg/m2) has been identified. As a result of the research work, it was recommended to grow parthenocarpic cucumber hybrids F1 Novator, F1 Sprinter, F1 Atos and F1 Avoska under conditions of unheated greenhouses of spring-summer turnover of the Kirov region.
