| Sumario: | Studies on 271 varieties of bean (Phaseolus vulgaris L.), randomly selected from the bean collection of the Tropical Higher Education and Research Center (IICA), showed that there is a close relationship between seed color and seedling color. This is most evident in black-seeded varieties, which produce red hypocotyls, cotyledons, and leaf veins, while white-seeded varieties produce the same organs in green. This correlation provides a key to predicting seed color from seedling color. In this way, a selection method can be developed to isolate potential mutants from black-seeded varieties in a mutation breeding program.
