In: Zagazig Journal of Agricultural Research 2003.v.30(3)Summary: The two F1,s of the two tomato crosses Money Maker x Castle Rock (MMxCR) and Carmeuco 200 x Peto 86 (C200 x Peto); and their parents were crossed with a group of 11 cultivars for each of the two crosses , to get 11 families for L1i,L2i and L3i sets of triple test crosses. The produced 33 families for each cross were tested under three micro-environments (30, 45 and 60 cm, plant spacing). Highly significant mean squares (M.S) for additive, dominance and epistasis and their interactions with the micro- environments were detected for final plant height, branch number, average early fruit weight, early fruit number, early yield,average fruit weight of total yield, total fruit number and total yleld/plant; except those of the interactions additive, dominance and ePistasis x environment for were fruit weight (in early yield) insignificant. Key wards: Genotype - environment interaction (GxE), triple test cross (TTC), additive, dominance, epistasis ,recombinant.
