Field and vegetable crop mutants with increased resistance to herbicides

Wheat mutants with increased seedling resistance to terbutryn (2-tertbutylamino-4-ethylamino-6-methylthio-s-triazine) and tomato mutants with increased resistance to diphenamid (N,N-dimethyl-2,2-diphenylacetamide) were selected by the experimenters out of populations grown from seeds treated with ethyl methanesulfonate. Induced mutations may thus provide a tool for breeding crop cultivars with increased resistance to certain herbicides.
