Major problem in agriculture is adequate seed storage due to difficulties in maintaining seed viability and vigour. Fifty French bean genotypes were taken to study the physiological basis of seed deterioration. The seeds were aged for 45°C and 100% RH and physiological parameters were recorded. Moisture content ranged from 9.697 % to 11.246 %. There was increase in moisture content across treatments. The speed of germination differed significantly among the different treatments. The fresh seed lot recorded significantly higher speed of germination. The values for control ranged from 24.21 to 74.46.The germination of French bean germplasm varied from 84% to 100%.There is a decrease in root length from control to four days of accelerated ageing. The root length ranged from 14.4 cm to 30.1 cm. The control seed recorded significantly higher root length, shoot length and seedling length than the treatments with different accelerated ageing conditions. There was decrease in shoot growth from two days accelerated ageing to four days accelerated ageing Vigour index for the control seed lots ranged from 3139.20 to 7290.00. After 72 h of ageing, all the varieties registered a significant decrease in vigour index I. After four days of accelerated ageing the seed vigour index I decreased drastically.
