Abstract
Ovate fruit is determined by a major recessive gene located in the first chromosome of the tomato. It is allelomorphic to both the round and the oblate types. These in turn are differentiated by a main factor and are allelomorphic to each other. This suggests a multiple allelomorphic series of genes controlling the oblate, round and ovate fruit shapes. Ovate shape (when contrasted with oblate) shows linked inheritance with dwarf growth habit, there being approximately ten or eleven per cent crossing over. There is also close linkage between ovate shape and the peach character of the fruit. High positive correlation exists between fruit shape (measured quantitatively by means of polar and equatorial diameter measurements) and fruit size, suggesting a linkage between shape factors and size factors on the first chromosome.
