Gene pools in Phaseolus and Vigna cultigens

  • J. Smartt
Article

Summary

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.
