Aim of work : to create the initial forms of cucumber at theuse of genotype of sort Nezhin local and on their basis tocreate the hybrid of cucumber with the complex of valuableeconomic signs (productivity not below 35 т/and, high tasteand pickling internalss, drought-resisting, relatively proof tomost illnesses); to estimate perspectivehybrid combinations in the nursery of competitive. Research object: гетерозисна selection of cucumber. Article of researches : collection, hybrid and plant-breedingmaterial The results of researches, that were conducted in 2016-2018 At the experimental station "Mayak" IVM NAAS was conducted plant-breeding work from creation of linearmaterial and hybrid of cucumber with the useof genotype of sort Nezhin local on condition of maintenanceof quality of garden-stuffs inherent to the Nezhin sort (taste,high closeness garden-stuffs, firmness insalting, attractive original appearance, considerable percentof standard product output), are presented in a post-mortemreport. For period of realization of plant-breeding work in 2016-2018a feedstock was studied in an amount 172 sorts andhybrids, in thereby in 2018 - 65. 1120 combinations ofcrossing are conducted, in т.ч in 2018 - 450. 210 hybrids ofF1, that is appraised in a hybrid nursery on a naturalbackground, are got. 126 hybrid posterities of 3-5th generation are appraised in aplant-breeding nursery, in thereby in 2018 - 41. Theselection of the best standards is conducted on the sexualtype of flowering of plants, productivity, precocity, тварностіgarden-stuffs, firmness to. In 2017 to NTSGRRU the line of cucumber is passed Mriya is distinguished by the high productivity of garden-stuffs: 40,0 т/and, that prevails a standard sort Source on12,9 from a mass stair to beginning of fruiting a 40twenty-four hours, at a standard a 42 twenty-four hours;period of fruiting of line a 58 twenty-four hours; firmness toпероноспорозу in a line Mriya is high are 7 points, that atthe level of standard; content of dry substance of4,42 sugar 2,14 ascorbic acid 13,70 mgs/of100г; nitrates 40 мг/кг; a tasting estimation of fresh garden-stuffs is 4,8 points salt - 4,8 points. A new line is intended forusing as paternal to the component at creation of hybrids ofcucumber nezhin. In 2018 the hybrid of cucumber is passed on state Eney F1 with the productivity of 38,8т/and, by a commodity product of the 82,7періодом fruitingoutput a 60 twenty-four hours, by firmness againstпероноспорозу 7 points, by the tasting estimation of fresh5,0 and salt garden-stuffs 4,9 points; content of drysubstance is 3,7 sugar 1,62 acid15,67 mgs/of 100 g; nitrates 133 мг/кг at a 3,481,4714,83mg/100 gs and 120 mg/kg at a standard; salt garden-stuffs isgeneral sugar 0,32 acid 8,33 mgs/of 100g; acidity of 1,42 1,81 Keywords: VEGETABLE-GROWING, SELECTION,CUCUMBER, CROSSING, PATERNAL LINES, HYBRID, ESTIMATION.
