This study was conducted to determine if the mutagenic agent, ethyl methane sulfonate (EMS), could be used to change the maturity of a soybean line while still maintaining the yielding ability and other morphological characters of the line. Mutants with changes in maturity have been reported in several experiments (Kawai, 1970); however, there are few reports where soybeans have been used in studies of this kind. In the study 1000 seeds of the cultivar 'Williams' were allowed to imbibe water for 16 hours by being soaked in distilled water that was aerated.
