Soybean ( Glycine max L.) is wellknown as a plant that posses an extra nutrition and many proteins and has a major role in improving people’s nutrition status. The environmental factors are the main obstacle in soybean production. High rainfall frequency can lead the waterlogging phenomenon which potentially decrease the production rate of soybean. Crop improvement are the best solution to solve the problems. The purpose of this research was to determine the tolerance level and physiological response of irradiated soybean, Grobogan and Anjasmoro varieties in waterlogging condition. 60CGamma were used to irradiate the seeds with 25Gy, 50Gy, and 100Gy dosages. This research were conducted in vegetative stadia with 100%, 150%, 200% concentration of water that dispersed into medium and control as comparison. Based on the data, the irradiation has a complex responses in plant morphology. The irradiated plant height was not significantly different among all treatments. While the leaf’s wide, root length, nitrogen in leaf, root nodules, chlorophyll content, fresh weight and dry weight are decline as the waterlogging concentration increased.
