The Genomic System of Classification as a Guide to Intergeneric Hybridization with the Perennial Triticeae

  • Douglas R. Dewey
Part of the Stadler Genetics Symposia Series book series (SGSS)


Of the approximately 325 species in the tribe Triticeae (= Hordeeae), about 250 are perennials that include many of the world’s important forage grasses. Although more than 75% of the species in the Triticeae are perennials, they have received far less attention from cytogeneticists and plant breeders than have the annuals, which include three major cereal crops--wheat, barley, and rye. In addition to being important in their own right as forages, the perennials form a vast genetic reservoir that might be used to improve the annual cereals.
