It has been noted (Dassou and Kueneman, 1984) that soybean varieties with colored seed frequently show tolerance to seed deterioration. In Brazil, naturally occurring, colored-seeded mutants of four soybean lines have been found. The existence of these near-isolines provided an opportunity to assess the role of seed color on seed deterioration in similar genetic backgrounds
