The present research was carried out on two genotypes of fenugreek viz. HM-57 and HM-103 with two seed lots of each genotype including fresh and one year old seed lot were stored under ambient condition and the observations were recorded at the interval of 3 months. In this experiment, both seed lots of two genotypes were tested for various physiological and biochemical basis for loss in viability and vigour. The hydration (6 h) and dehydration at room temperature followed by dry dressing with thiram (0.25%) recorded significantly maximum germination over the treatments throughout the storage period in both varieties and seed lots showed higher improvement in all laboratory and field parameters followed by hydration-dehydration treatment. Lot (L2) seeds showed better improvements over lot (L1) for standard germination, root length, shoot length, vigour indices, viability, Electrical conductivity. Whereas L1 seed lots showed better improvement in test weight, seed density, seedling dry weight. The variety HM-57 showed higher improvement in test weight, seed density, standard germination, root length, vigour index-I, whereas HM-103 showed higher improvement in shoot length, seedling dry weight, vigour index-II.
