Taxonomy of grain legumesR MPolhillauthorL J Gvan der MaesenauthorThe taxonomy; of grain legumes is relatively uncomplicated compared to that of cereals, brassicas and some other groups of plants because, in general, only limited gene pools have been available for selection and subsequent plant breeding. Then again, intergeneric legume hybrids are not known in nature and artificial crosses attempting to create them are seldom, if ever, successful [64]. Indeed, the genetic barriers between species and species groups are often substantial [86,87]. The classification' of interfertile species and infraspecific variants is inherently more difficult and the taxonomic situation in grain legumes is not exceptional. In some instances the available information would now seem to justify updating of the taxonomic framework.Legume Crops1985-10Sheridan House IncBook Section
