Mutant, induced by a 0.06% concentration of ethylene-imine in cucumbers, is characterized by a general gigantism, particularly of leaves, flowers and seeds which frequently attain two-fold larger size than the initial forms. Cytoembryological studies showed that the mutant had a diploid chromosome number, a little lower pollen fertility and considerably reduced seed fertility. That last character is likely to be a result of irregularities in the development of the mutant embryos. A genetic analysis showed that the described changes are determined by a single recessive gene, designated as gig
