Gliadins and glutenins of several durum wheat cultivars and lines from various countries were analyzed by two different elctrophoretic techniques, in order to study the variation of protein components associated with quality. Most of the material possessed either y-gliadin component 42 or y-gliadin component 45, along with their respective clusters of linked w-gliadin components and low-molecular-weight glutenin subunits LMW-1 or LMW-2. The presence of recombination in which band 42 was present along with the w-component usually linked to band 45 was found in the Italian durum wheat cultivar Berillo. Materials in which possible forms alternative to the combination 42/LMW-1or 45/LMW-2 were also observed. Variation in high molecular weight glutenin subunits at the Glu-A1 and Glu-B1 loci was also found.

Abstract
Gliadins and glutenins of several durum wheat cultivars and lines from various countries were analyzed by two different elctrophoretic techniques, in order to study the variation of protein components associated with quality. Most of the material possessed either y-gliadin component 42 or y-gliadin component 45, along with their respective clusters of linked w-gliadin components and low-molecular-weight glutenin subunits LMW-1 or LMW-2. The presence of recombination in which band 42 was present along with the w-component usually linked to band 45 was found in the Italian durum wheat cultivar Berillo. Materials in which possible forms alternative to the combination 42/LMW-1or 45/LMW-2 were also observed. Variation in high molecular weight glutenin subunits at the Glu-A1 and Glu-B1 loci was also found.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
