Technical Abstract: Soybean lines differ in their tolerance to both complete submergence and root flooding. Tolerance to complete submergence is an innate ability that occurs at the biochemical level and allows the seedlings to survive short durations of submergence. Tolerance to root flooding depends on the adaptation ability of the plants to develop mechanisms for transportation of oxygen to the roots. Tolerant plants not only survive, but also grow normally during extended periods of root flooding. The correlation coefficient of tolerance to submergence and tolerance to root flooding under greenhouse conditions was 0.7 and tolerance to field flooding was 0.5. Under field conditions, tolerance to diseases that are prevalent in flooded soil may play an important role in the growth and productivity of soybean.
