Abstract: Seed quality enhancement through seed priming was attempted in two different vigour level lots of tomato (Lycopersicum esculentum) var. PKM 1 at the Department of Seed Science and Technology, Agricultural College and Research Institute, Madurai. Two seed lots with the initial seed germination of 79 and 44 per cent and the vigour of 1610 and 539, designated as high and low vigour lots, respectively were selected and subjected to different seed priming treatments viz., hydropriming, GA3 50 ppm, KNO3 1%, KH2PO4 4%, succinic acid 300 ppm. The results revealed that the seed priming treatments have significant role in seed quality enhancement as evidenced by the germination improvement from 79 to 92 per cent by succinic acid 300 ppm and the vigour improvement from 1610 to 2243 in the high vigour lot. In the low vigour lot, the germination improvement from 44 to 72 per cent and vigour improvement from 539 to 1348 was recorded using KH2PO4 and the succinic acid 300 ppm recorded 68 per cent germination and 1104 vigour index.
