Abstract: Pods and kernels of two genotypes (GPBD-5 and DH-86) of summer groundnut were subjected to the accelerated ageing at 40o C and 90 % RH for various intervals (0, 2, 4, 6, 8 days). Accelerated ageing results in progressive loss of seed viability and vigour in both genotypes. A marked genotypic difference in storage of both genotypes in the form of pods and kernels on ageing had been recorded. Germination test and biochemical analysis were carried out for control and aged pod and kernels. The initial germination percentage was 97.86 % and after accelerated ageing germination decline to 49.32 %. During the ageing process decline in oil percentage and total soluble protein, whereas increase in total soluble sugars and phenols content was recorded. There was gradual decrease in the activity of β-amylase and increase in the activity of lipase was recorded during accelerated ageing. Hence the decrease in the changes in the biochemical content and the activity of enzymes involved in the degradation of seed reserves.
