Soybean [Glycine max. (L.) Merr] is one of the most important legumes in the world. However, soybean varietiesare sensitive to flooding stress and their seed yields are substantially reduced in response to the flooding stress. 192 soybeangermplasm collection was screened to identify flooding tolerant germplasm at an early vegetative growth stage (V1). Soybeanplants at V1 stage were waterlogged for 4 to 10 days. To evaluate flooding tolerance, survival rate were investigated as a timedependent manner. Jangbaegkong, Danbaegkong, Sowonkongkong, Socheong2 and Suwon269 showed flooding tolerance, whileShillog, T201, T181, NTS1116 and HP-963 showed flooding sensitivity. We also investigated effects of flooding stress onsoybean morphology. The adventitious root development was greatly increased in flooding tolerant plants compared to it inflooding sensitive plants. In addition, root length and root number were analyzed. The significant reduction of root length androot number was observed in flooding sensitive plants. Thus, these results indicate that the morphological changes in roots areimportant for acclimation to flooding stress. Taken together, the relationship between the morphological changes in the roots andflooding tolerance may be useful in selecting a flooding tolerant soybean germplasm.
