The effect of temperature on spore germination of Uromyces viciae fabae (Pers.) de Baryon pea plant was studied using cavity slide germination method at different temperatures like 10, 15, 20, 25 and 300C and spore viability was studied by germination test employing cavity slide technique at 10, 15, 30, 60, 90, 120, 150, 180 and 240 days after storage at different temperatures i.e. 15, 20, 25, 300C in incubator and at 5 to 100C in refrigerator. The result indicated that maximum germination of aeciospore, urediospore and teliospore was observed at 20 0C temperature. At 5 0C storage temperature, the survival of aeciospore, urediospore and teliospore was found maximum for 60, 120 and 240 days, respectively.
