Outline of Final Research Achievements

1. In yellow soybean cultivar with the I/I genotype, the occurrence rate of pigmented seeds by the pigmented mutation was very low. 2. In yellow soybeans with the Ic/Ic genotype, the occurrence rate of pigmented seeds by the pigmented mutation may be lower than that in yellow soybeans with the I/I genotype. 3. Defective cracking frequently observed in the pigmented seed coats of the pigmented mutant was suggested to be due to lignin deposition. 4. A DNA marker to distinguish between the I/I genotype and the i/i genotype was developed.
