Identification of a Gene Affecting Pedicel Orientation in Tomato1

A mutant of the tomato (Lycopersicon esculentum Mill. cv. Flora-Dade) was characterized by straight pedicels oriented in an upright position. A genetic study indicated the mutant character was controlled by a single recessive gene, which has been tentatively designated as up-right pedicel (up). The up locus is linked to the jointless pedicel (j-2) character of ‘Flora-Dade’, with a crossover distance of 8.5 units.
