The percent of outcrossing on oat plants from untreated and mutagen‐treated seeds was determined from four experiments. The mutagens used were thermal neutrons and ethyl methanesulfonate. The year‐to‐year percent outcrossing varied from 2.4 to 6.0 in the mutagen‐treated populations and 0.5 to 2.4 in the checks. The mean outcrossing percents for all experiments were 4.0 and 1.4, in the mutagen‐derived and check populations, respectively. Both mutagens, when applied in proper dosages, were equally effective in causing outcrossing.
