Seed lots with different viability levels were needed in seed invigoration. The objectives of this research were to find out the method of Chemical Accelerated aging that could produce the desirable cucumber seed lot with 80% and 60% germination percentage, and the storability of the treated seeds. Seeds of three cucumber varieties (Misano, Monza, and Penus) were treated by different soaking duration in liquid ethanol 96% to produce 80% and 60% viabilitiy levels and then storedin ambient room (25-30 ºC and RH 57-75%) and AC room (20-28 ºC and RH 45-74%). Cucumber seed of varieties Monza, Misano, dan Penus with viability level of 80% (VL1) could be obtain by soaking the seed into ethanol liquid 96% for 80 minutes, 10 hours 48 minutes, and 4 hours, whereas those with viability level of 60% (VL2) were obtained by soaking duration of 170 minutes, 14 hours 44 minutes and 7 hours. Storage experiment showed that in ambient condition both viability level of Monza seed could maintained the viability for 4 weeks, Misano seed 2 weeks, whereas Penus seed 8 weeks. In AC condition Misano and Penus seed could maintained the viability for 8 weeks, whereas Monza seed 6 weeks.
