Parental seed production in tomato, number of fruits retained on seed parent and pollen parent will decide not only seed yield but also seed quality. Application of growth regulators like GA3, NAA are known to modify plant morphophysiological characters and help in getting higher seed yield coupled with better quality traits.Among growth regulators GA3 100 ppm recorded significantly higher fruit yield/plant (1206.01g), seed yield/plant (8.12 g) and germination (90.92%) and vigour index (1424) over control (1101.69g, 7.36g, 87.60% and 1301, respectively) Retention of all fruits recorded higher fruit yield (1824.79g) and seed yield/plant (11.38g) compared to 10,15 and 20 fruits. Germination (91.51%) and vigour index (1460) were significantly higher in 10 fruits per plant compared all fruits treatments. Among the treatment combinations, GA3 100 ppm with retention of all fruits recorded significantly higher fruit yield/plant (1898.10g), seed yield/plant (11.95g). vigour index (1501) was significantly higher in GA3 100 ppm with 10 fruits compared to other treatment combinations.Keywords
