Abstract
The proteins extracted from etiolated seedlings of 10 accessions, representatives of the species of the Sitopsis section of Triticum were analyzed by two-dimensional (2D) gel electrophoresis. The 2D patterns were compared and similarity indices were computed between all accessions. From the similarity matrix a dendrogram was deduced, that gave interesting information concerning the genetic relationships between the species of the Sitopsis section. The 2D pattern obtained from the Chinese Spring variety of Triticum aestivum was then included in the analysis. From the dendrogram obtained and also from the number of species-specific proteins shared between Chinese Spring and each of the Sitopsis species, it is proposed that the B genome donor of the cultivated wheats originated from a species closer to the T. speltoides-T. aucheri group than to any other diploid Sitopsis species.
