Abstract

Previous studies have shown that chromosomal rearrangements largely influence changes in the genetic information found in the genus Avena (oat). Examinations of approximately 90 accessions of A. sterilis, the wild ancestor of A. Sativa and A. byzantina, using C-banding and molecular genetic markers previously revealed Turkey and Upper Mesopotamia to be the likely center of origin of the two cultivated oat taxa (2). E. N. Jellen identified a chromosome crossing between chromosomes 7C and 17 which predated the domestication of cultivated hexaploid (six copies of each chromosome) oat taxa A. sativa and A. byzantina( 1).
