IN normally monœcious melons (bearing both male and female flowers) the occurrence of andromonœcious (mostly staminate with fewer perfect flowers), hermaphroditic (all perfect flowers), and even gynomonœcious (mostly pistillate with fewer staminate or perfect flowers) plants have been reported1. The latter type would be of considerable value in genetic work. Previous attempts to establish genotypically pure female lines have failed owing to the difficulty of obtaining pollen for inbreeding. In the recorded work here, it is reported that grafting of a gynomonœcious scion to selected andromonœcious understocks will temporarily induce formation of male flowers on the gynomonœcious scion.
