Abstract: 20 soybean genotypes were selected for evaluating the biochemical changes on seed longevity. 5 different testa coloured soybean genotypes had used for the experiment. 20 different soybean genotypes were stored in polythene bags of 400 gauges for 10 months. Different biochemical parameters were analysed before the seed storage and on monthly intervals. Among them, Black coat seeds had showed resistant for seed longevity and yellow coloured genotypes exhibited susceptibility for seed longevity. All the soybean genotypes showed a significant difference for total soluble sugars, crude protein (%), amylase activity and peroxidase activity. Among the different genotypes, black seed coated soybean EC-76756 showed highest peroxidase activity (0.998 and 0.703), crude protein (38.89% and 27.24%), amylase activity (0.198 to 0.157) and lowest total soluble sugars (93.46 to 118.69 µg/ml of seed leachates) from initial month of seed storage to 10th month of seed storage respectively. And the lowest peroxidase activity, crude protein, amylase activity and highest total soluble sugars were recorded by yellow colour soybean seeds in both initial and 10^th month of seed storage.
