Genetical studies on fruit weight, equatorial diameter and polar diameter of fruit, fruit shape index, locules/fruit, TSS content of fruit juice, length of style, ovary diameter and pollen diameter were made in the F1 and F2 populations of an interspecific cross L. pimpinellifolium x L. esculentum of tomato. The parents represented a wide range of variation for all the characters. Characteristics of F1 and F2 populations varied in different characters. However, in all the character genes with negative effect exhibited dominance in both F1 and F2 populations. Group of genes detected for fruit weight were 22-29, for equatorial diameter 11-13, for polar diameter 8-10, for style length 5-7, for pollen diameter 5-8 and 2 groups of genes for locules/fruit and TSS of fruit juice. Only one group of gene was detected for fruit shape index and ovary diameter. Fruits borne by few F2 segregates were medium sized, round to slight flatlish, shiny red and having appreciable TSS content in the fruit juice.
