A total of 173 samples of domestic germplasm of common beans species and 118 selection lines and cultivars were tested. The objective was to establish the effect on the distribution of genotypes of Andean and meso-American gene pools, including the phaseolin types, that distribute them in these two groups, on the one hand and on the other – the morphological indexes – seed and pod shape.
Spherical and elliptic shapes are the most common in domestic germplasm. In the working collections, 97% of the selection lines and cultivars are of elliptic shape. In domestic samples, flat-orbicular pod shape prevails followed by the flat one. In selection materials, both flat and orbicular shapes are observed. It was established that the distribution of Andean and meso-American gene pools depends on seed shape. Gene pools distribution does not depend on pod shape. There is no relationship between the phaseolin type and the morphological characteristics studied.
Key words: Phaseolus vulgaris L., gene pools, phaseolin types, seed shape, pod shape
