I report coleoptile color variation observed in Aegilops tauschii accessions collected in the Caucasus, Turkey, and Syria.  Sixty-eight accessions were used in this study (Table 1).  These accessions were the collections of the Centre for Genetic Resources (CGN accessions), Institut fur Pflanzengenetik und Kulturpflanzenforschung (AE accessions), International Center for Agricultural Research in the Dry Areas (IG accessions), Plant Germ-plasm Institute (KU accessions), and United States Department of Agriculture (PI accessions).  In December of 2003 and 2004, seeds (one per accession) were sown and the plants grown individually in pots in a slightly-heated greenhouse at Fukui Prefectural University.  Coleoptile color was checked by eye and recorded as red (i.e., anthocyanin pigmentation) or green (i.e., no anthocyanin pigmentation).  One accession (IG 127015, Armenia) had green coleoptile, whereas all the other had red coleoptile (Table 1).  I thank H. Bockelman (PI accessions), A. Graqner (AE accessions), T. Kawahara (KU accessions), J. Konopka (IG accessions), J. Valkoun (IG accessions), and L. Visser (CGN accessions) for the seeds.
