| Research Abstract |
In yellow soybean, seed coat discoloration occurs when plants are exposed to low temperature after the onset of flowering, a phenomenon named cold-induced discoloration abbreviated as CD. CD reduces the commercial value of yellow soybean, and therefore DNA markers are required tocreate CD-tolerant cultivars. However, it was not even known how low temperature causes discoloration in the seed coat. In this study, we investigated the occurrence and tolerance mechanisms of CD. Furthermore, based on the findings, we developed a DNA marker being effective in selecting the CD-tolerant plants.
