Genetic evidence has demonstrated the presence of a major factor for fruit size in the first linkage group of the tomato, linked inheritance being exhibited between fruit size and the genes for the tall-dwarf and the smooth-peach (pubescent) characters. In this same linkage group a major gene for fruit shape (ovate) has been found.
