The results are presented of a study of the effect of ethrel (2-chloroethanephosphonic acid) on the sex and seed yield of varieties belonging to different geographic groups. When varieties with both sexes of flowers were treated with ethrel, the number of male flowers was markedly reduced and the number of female flowers increased. Seed yield changed little after treatment with ethrel.
