| Résumé: | Copyright © 2009 Elsevier Ireland Ltd. All rights reserved. In soybean (Glycine max [L.] Merr.), varieties with seed-flooding tolerance at the geminating stage are desirable for breeding in countries with much rainfall at sowing time. Our study revealed great intervarietal variation in seed-flooding tolerance as evaluated by germination rate (GR) and normal seedling rate (NS). Pigmented seed coat and small seed weight tended to give a positive effect on seed-flooding tolerance. Subsequently, QTL analysis of GR and NS were performed and a total of four QTLs were detected. Among them, Sft1 on the linkage group H (LG_H) exhibited a large effect on GR after a 24-h treatment; however, Sft2 near the I locus on LG_A2 involved in seed coat pigmentation exhibited the largest effect on seed-flooding tolerance. Sft1, Sft3 and Sft4 were independent of seed coat color and seed weight. Based on the results, we discussed the physiological effects of genetic factors responsible for seed-flooding tolerance in soybean |
