This paper describes findings in the characterization of 300 accessions in a collection of common beans (Phaseolus vulgaris L.) in Honduras. The plant material was collected from 1990 to 1994 (4 years before the damaging Mitch Hurricane) covering most of the Departments of the country and kept at the Escuela Agrícola Panamericana Zamorano. Thirty-two morpho-agronomical characters were evaluated and the results were grouped by classes. The studied accessions showed a marked diversity with high predominance of red and small seeds. The accessions with purple flowers had black seeds and originate mainly from the western area of the country where this type of seed is preferred. Principal Component Analysis shows that clearly defined groups do not exist. The conservation of this diversity is recommended for future propagation, breeding and the investigation of the genetic relationships and other studies.
