✦ Synopsis
The mutual resemblance of 81 hexaploid wheat plants contaminating durum fields on Cyprus was investigated by determining their phenotypes of gliadins, glutenins and peroxidase . Three groups were generated by clustering programs . Group 1 consists of plants with ears resembling those of durum plants, plants of groups 2 and 3 have a bread wheat appearance . Suggestions on the origin of these three groups are made . Group 1 may derive from (back)crosses between hexaploid and durum plants since time immemorial . If so, the hexaploid plants would have served as donor' of the D genomes, and durum plants as the recurrent parent' . Groups 2 and 3 may derive from two introductions, either from two countries, or from the same country, but then in different periods .
