| Outline of Final Research Achievements |
We aimed to clarify phenotypic variation in root development under hypoxia condition at the seedling stage using diverse soybean accessions. Root development in 162 accessions was evaluated in hydroponic culture.
We found significant phenotypic variation in hypoxia tolerance in root among the 162 accessions. Principal-components analysis indicated an association between hypoxia tolerance and the country of origin. Root development in selected accessions was also evaluated in soil culture. Root development levels in hydroponic and soil culture were significantly correlated. These results will provide important information on waterlogging damage in regions where waterlogging occurs.
