Variation of HMW glutenin and ?-gliadin subunits in selected accessions of Triticum dicoccon (Schrank) and T.spelta (L.).

Ten accessions of emmer (T. dicoccon Schrank) and ten of spelt (T. spelta L.) have been analysed, using electrophoresis, for their HMW glutenin subunits and ?-gliadin fraction. Emmer has been discovered to be more polymorphic than spelt. The highest variation has been associated to HMW glutenins. New alleles, provisionally assigned to Glu-Al and Glu-Bl loci have been detected in some accessions of emmer. The whole meals of tested accessions were also analysed for protein content and SDS-sedimentation test. Relationships between the SDS-test value, the quality index and the electrophoretic pattern are also discussed.
