Tomato is a unique crop which provides a variety of processed products, namely, juice, paste, puree, soup and ketchup, etc. Processing characters vary significantly with that of table use. F, hybrids suitable for processing attributes are in great demand and are less available commercially. Lycopene is the pigment principally responsible for the characteristic deep red colour of ripe tomato fruits and tomato products. The main causes of tomato lycopene degradation during processing are isomerization and oxidation. Isomerization converts all trans-isomers to cis-isomers due to additional energy input and results in an unstable, energy-rich station. Determination of the degree of lycopene isomerization during processing would provide a measure of the potential health benefits of tomato-based foods. The final experiment was carried out with 10 sets of parents and its crosses in a compact family block design during 1999 at NDUA and T, Faizabad. Significance of additive as well as dominance gene effects and I, j and 1 types of non-allelic gene interaction was observed in the crosses H-24×NT-2, H-24×DVRT-1, H-36×NT-2, H-36×MM, H-36×Labonita and H-36×DVRT-1. Additive gene effects and I, j and 1 types of gene interaction were recorded for the crosses H-24×MM, H-24×NT-1 and H-24×Labonita, while additive and dominance gene effects and I and j types of interactions for the cross H-36×NT-1. Duplicate epistasis was present for the crosses H-24×NT-2, H-24×DVRT-1, H-36×NT-2, H-36×MM, H-36×Labonita and H-36×DVRT-1 for these traits. Total soluble solids TSS showed that the additive (d) and dominance (h) gene effects and I, j and 1 types of gene interactions were significant for the crosses H-24×NT-2, H-24×MM, H-24×NT-1, H-24×Labonita, H-36×NT-1 and H-36×DVRT-1. Significance of additive (d) and dominance (h) gene effects, I and 1 type of gene interaction for H-24×MM; (d), I, j and 1 type of gene interaction for H-24×DVRT-1; additive (d) and j type of gene interaction for H-36×MM and additive and dominance gene effects and j type of interaction for H-36×Labonita were observed.
