title: [Mutagenic activity of nitrosoalkylureas and diazoketones on corn. I].
abstract: Among the nitrozoalkylureas studied, nitrozoethylurea proved to be the most effective in respect to the frequency of induced chromosome aberrations. Diazoketones, except for bis-diazoacetyl had a negligible effect on the chromosome structure. As to the frequency of induced visible mutations (M1-M3) diazoacetone, nitrosodiethylurea, bis-diazoacetyl and nitrozodimethylurea (88.8-54.3% of mutations) were the most active among 10 studied mutagens.
