N-nitroso-N-methylurea and ethyl methanesulphonate were applied to populations and inbred lines of monosulphonate were applied to populations and inbred lines of monogerm sugar beet. The M1 generation was selfed and M2 progenies were obtained which contained mutant individuals. The size of the M2 generations was sufficient to permit selection. Chlorophyll mutations were the most common in the M2 occurring at a frequency of approximately 1%.
