Outline of Final Research Achievements |
Yellow soybean shows yellow color due to suppression of seed coat pigmentation. Sometimes in the seed production of yellow soybean cultivars, seeds are pigmented by virus infections or low temperatures. These seed coat pigmentation phenomena, which reduce seed commodity value, are called "seed mottling" and "cold-induced discoloration (CD)", respectively. In this study, we investigated whether a highly CD-tolerant cultivar Toyoharuka is also tolerant to the seed mottling. As a result, cv.Toyoharuka was shown to diminish the extent of SMV seed mottling as well as CD, suggesting that cv.Toyoharuka can be a useful breeding material.
