We have confirmed data regarding the action of γ-hexachlorcyclohexane as an agent inducing polyploidy, established a simple method of its application, determined the extend of its effect and found out whether it would be possible to replace the colchicine technique by a more accesible method of γ-HCH application. The method resulting from preliminary experiments with onion and lettuce was later applied to species and varieties of a number of plants (see list). The activity of γ-HCH as an agent inducing polyploidy was confirmed by the experiments. A method of sowing seeds in a damp film of γ-HCH was projected forLinum usitatissimum, Viola tricolor maxima aLactuca sativa. It seems probable that the use of γ-HCH instead colchicine pretreatment will be possible in cytological technique.
