Diversity of seed storage protein patterns of Slovak accessions in jointed goatgrass (Aegilops cylindrica Host.)

Variations in seed storage protein patterns were investigated for six accessions of jointed goatgrass (Aegilops cylindrica) populations collected from Slovakia within the framework of the bilateral Co-operation in Science and Technology between the Slovak Republic and Hungary. The study covered populations collected from the southwestern (localities: Sered and Dunajská Streda), southern (localities: Chlaba and Kamenica nad Hronom) and southeastern (localities: Cierna nad Tisou and Dobra) parts of Slovakia. Analysis of profiles of seed storage proteins – glutenins and gliadins – was carried out using acid polyacrylamide gel electrophoresis and sodium dodecyl sulphate polyacrylamide gel electrophoresis. All accessions have a uniform three-band high molecular weight glutenin pattern with CxCyDy subunit composition. The highest variations in gliadin bands among the populations were observed from Cierna nad Tisou. There were small differences among the populations from Chlaba and Dobra. The lowest variations were in populations from Sered, Dunajska Streda and Kamenica nad Hronom. The present investigation showed that these jointed goatgrass populations are valuable genetic resources for wheat crop improvement programmes.
