| Abstract: | Emmer wheat (Triticum turgidum ssp. dicoccum Schrank) is hulled wheat that survives in marginal areas of the Mediterranean Region. The HMW and LMW glutenin subunit composition of 97 accessions of emmer wheat from Spain have been analysed by SDS-PAGE. For the HMW glutenin subunits, four allelic variants were detected for the Glu-A1 locus; one of them has not been previously described. For the Glu-B1 locus, three of the nine alleles detected have not been found before. A high degree of variation was evident for the LMW glutenin subunits, and up to 23 different patterns were detected for the B-LMW glutenin subunits. Considering both types of proteins (HMW and LMW), 30 combinations were found between all the evaluated lines. This wide polymorphism can be used to transfer new quality genes to wheat, and to widen its genetic basis. Received: 13 June 2000 / Accepted: 3 July 2000 |
