Abstract
Environmental and genetic control of heterostyly or exserted stigma in the tomato has been observed by previous investigators (2, 4, 6, 7). Flowers developing subsequent to gibberellin treatment have been reported to have a similar effect (1). In the cross between a responding variety, Indian River, and non-responding variety, Fireball, the F1 showed stigma exsertion due to gibberellin treatment. From an analysis of the F2 and backcross segregation it was found that this response was conditioned by a single dominant gene. This gene was assigned the gene symbol Gx. There was no linkage between this character and uniform fruit, u, and self-pruning habit, sp.
