Abstract

The seed storage protein composition of one collection of cultivated einkorn wheat (Triticum monococcum L. ssp. monococcum) of Spanish origin has been analysed by SDS-PAGE and A-PAGE. Three allelic variants were detected for the Glu-A1m, whereas up to six alleles were detected for the Glu-A3m. For the gliadins, 7 and 14 alleles for the Gli-A1m and Gli-A2m were found between the evaluated accessions. Internal variability was detected in some of these materials, which could be related to the landrace nature of them. Up to 48 different genotypes based on the origin and seed storage protein composition have been identified. Further researches on these materials must be carried out for determining the variability degree in morphological traits that could complement the evaluation for their safeguard.
