Objective: To identify valuable triple heterosis hybrids of cucumber, create new lines for heterosis breeding work out methods of selection. Methods: sexual hybridization, individual and family selection for provocative backgrounds peronosporozu and the elevated temperature; Field, measurement and weighting, statistical matematychno. Results: methodical approaches of heterosis breeding of cucumber on the specifics of parental forms and create stable triple hybrids. To expand the gene pool is created and passed to NTSHRRU 2 line cucumber: maternal triple hybrid 107-3 CMF - hinoetsiynist 86% Early (41 days), heat-resistant (7 b.) Peronosporozu and resistant to bacteriosis (7 b.). Men line - tsp 5317-1, hinoetsiynist - 13%, providing a high percentage of perezapylennya parent form (95-98%), yielding, early maturing (38-40 days), resistant to bacteriosis peronosporozu and (7 b.). pairs of isogenic lines highlighted a cucumber for use in heterosis breeding, as well as a valuable source material for h.-ts. features: saturation female plants - 9; by ripening - 12 yield for the first decade of fruiting - 38, for stability - 50. competitive with nursery studied three hybrids F1. Highlight hybrid combination [(ZHL 10 x 2 L) x L 1], which significantly exceeded the standard for F1 Troy yield (37.7 t / ha), and the marketability, resistance against peronosporozu and for ripening - was at the level of the standard. Keywords: cucumber, breeding, heterosis, hinoetsiynist, resistance peronosporozu.
