A wild race of Phaseolus vulgaris L. as a new source of phaseolin variation

A wild race ofPhaseolus vulgaris from Mexico exhibited a phaseolin pattern very similar to that ofPhaseolus coccineus. Most likely, this accession resulted from introgression ofPh. coccineus intoPh. vulgaris. The greater variation with respect to phaseolin in wild races of the common bean is confirmed. Wild material can be considered as a useful source for breeding purposes.
