Four growth type mutants 2-75, W-SK, W-19, W-97 obtained from seeds of Cucumis sativus var. Borszczagowski treated with ethylene imine were studied. These mutants represented two types of growth: intensive (2-75) and dwarf (W-SK, W-19, W-97). The exuberant growth of mutant 2-75 was the result of internode elongation, intensive production of lateral shoots, enlargement of leaf and number of vascular bundles (11 as compared with 9 in the remaining mutants). The dwarfness of W-SK, W-19, W-97 mutants was caused by strong shoot reduction resulting from decreased length and number of internodes, limiting of lateral shoot production, smaller and darker leaf blade. The mutants produced fruits which differed in shape, dimension and colouring. Moreover, the fruits of mutant 2-75 were characterized by the presence of empty chambers in the endocarp
