Abstract
Phleum is a complex genus involving diploid, tetraploid, hexaploid and octoploid forms. The domesticated forms of Phleum pratense, known as Timothy, are usually hexaploid. There is now considerable potential to introgress and to resynthesize new forms using wild relatives from other ploidy levels of the section Phleum using the knowledge gained about their relationships from molecular studies. Germplasm of many of these forms is under serious threat from habitat degradation and climate warming. Unfortunately many of these forms, particularly those from the Mediterranean and North Africa, are absent from genebanks and their collection for storage in ex situ genebanks is essential.
