Abstract
Although the diploid species Avena canariensis has a number of morphological features in common with the hexaploid species of Avena, the degree of chromosome pairing in the tetraploid hybrid A. canariensis × A. sativa did not reveal closer homology with A. sativa than that of another diploid species, A. prostrata. The chromosomes of both these newly described diploid species are only partially homologous with one of the genomes of A. sativa. The two diploid species A. prostrata and A. canariensis are differentiated by translocations involving three pairs of chromosomes.Keywords
