Acoustic emission(AE) method was applied to assessment of soybean flooding tolerance at germination. Frequencies of elastic waves, accompanied by microfracture inside the immersed soybean seeds, were counted and evaluated its relationships to seed germination ratio after one-day water immersion using recombinant inbred lines. There was a significant difference in the AE frequencies between the normal germinated population and the poorly germinated population, but no relationship between the AE frequencies and the flooding tolerance was found and no valid QTL was detected. We expect localized AE frequeicies, such as in cotyledonary nodes not whole seed, manifest the relationships to flooding tolerance.
