Purpose: to create original forms cucumber using genotype variety Nijinsky local and, based on a hybrid cucumber with a set of economic variables (yield not less than 35 tonnes / hectare, high taste and zasolyuvalni quality, drought-resistant, relatively resistant to most shkodochynnyh diseases); evaluate promising hybrid combinations in the nursery competitive sortoispytanija. Object of study: heterosis breeding of cucumber. Subject of research: collection, hybrid breeding material and cucumber. The final report presents the results of studies that were conducted in 2011-2015. At the experimental station "Mayak" IOB NAAS held breeding work on creating linear material heterosis and hybrid cucumber genotype variety using local Nijinsky while maintaining fruit quality inherent Nizhynsky grade (taste, high density and hrustkist fruits, resistance to salting, attractive appearance, a significant percentage of output conditioning products). During the period of breeding work in 2011-2015. Studied source material in quantities of 244 varieties and hybrids, including in 2015 -47. A mating combinations 1670, incl in 2015 - 333. 315 obtained hybrids F1, evaluated in a hybrid nursery natural background. In breeding nursery hybrid progeny evaluated 203 3.5-generation, including in 2015 - 17. A selection of the best specimens for sexual type of flowering plants, yield, precocity, createdness fruit resistance against peronosporozu, tasting fresh and saline assessment fruit. In 2013 NTSHRRU transferred to Youghal cucumber line that features high yields fruit: 38.0 t / ha, the predominant source grading 12.9%, the period from the beginning of mass germination to fruiting 40 days, the standard 42 days; line fruiting period 58 days; peronosporozu resistance at high line Youghal - 7 points, at the level of the standard; dry matter content of 4.42%; total sugar 2.14%; ascorbic acid 13.70 mg / 100g; nitrates of 40 mg / kg; fresh fruit tasting score - 4.8 points, salty - 4.8 points. The new line is designed for use as a parental component in creating hybrids of cucumber Nijinsky sort types. In 2015 transferred to the state sort testing F1 hybrid cucumber Sarmat yield of 42.2 t / ha yield marketable products 85.8%, fruiting period of 60 days, resistance against peronosporozu 7 points, tasting score salt and fresh fruits 4.9 points ; dry matter content of 4.23%; total sugar 2.09%; Ascorbic acid 11.62 mg / 100g; nitrate 44.05 mg / kg at 3.95%, 1.58%, 9.69 mg / 100 g and 69.9 mg / kg standard; pickled fruits - total sugar 0.32%; Ascorbic acid is 8,33 mg / 100g; 0.75% titrated acidity, salt 2.59%.
