The nature and extent of the gene pools in cultigens of the genera Phaseolus and Vigna, as indicated by studies of experimental interspecific hybridization, are reviewed. In all cases a primary gene pool exists comprising conspecific wild and cultivated forms.
Secondary gene pools have been established for Phaseolus vulgaris-Ph. coccineus, Vigna radiata-V. mungo and V. angularis-V. umbellata but not for V. unguiculata and for Voandzeia subterranea. Tertiary gene-pools apparently exist for all Phaseolus cultigens and the Asiatic grams but not for V. unguiculata and V. subterranea as far as is known.
