Creole seeds should be studied and valued, since they can contribute to the improvement of the productive, commercial and feeding aspects of family farmers. The objective of this study was to evaluate the physiological and physical quality of bean seeds from the Regional Seed Bank. Creole seeds came from the Regional Seed Bank (BSR) of the Caiana community in Brazil. The seeds were submitted to germination and vigor analysis, germination speed index, root and shoot length, green and dry mass of normal seedlings, moisture, weight of seed, seed mass, apparent and real density, porosity, seed volume and colorimetric parameters (L*, a*, b*, Chroma C* and darkening index). The varieties Owl and Blue presented higher physiological quality and the Sedinha variety presented greater weight of one thousand seeds, greater apparent and real density, as well as porosity and humidity in relation to the other varieties.
