Triploid lines of cucumber were studied with a view to its commercialization. The average of total and commercial yield per plant varied between triploid crosses. However, the mean yield difference between homo- and heterozygous triploid was not significant. Classification of yields according to fruit length and diameter revealed that triploid yields were mostly assigned to the first and second class. The taste of triploid fresh fruits varied between the crosses, but their fragrance was the same in all line crosses. The sensory tests of triploid pickled fruits and their flesh firmness varied between homo-and heterozygous triploid. However, the pickled fruits of triploid had a slightly better taste, fragrance and had extra firm flesh as compared with the fruits of diploid cv. Polan F1. The resistance of triploid plants to downy mildew disease was highly variable between crosses. However, the cross combinations of line 603 showed the least susceptibility to the downy mildew disease.
