Romanian wheat (Triticum aestivum L.) landraces characterized by seed storageprotein electrophoresis

摘要

Forty Romanian wheat landraces, stored in the active collection of the Suceava Genebank, were characterized by means of glutenin analyses. Their HMW-GS patterns, homogeneity and heterogeneity, and Glu-score were determined and characterized by SDS-PAGE. Seed storage protein patterns analysed in this study indicate a relatively high level of protein heterogeneity. Only five of the accessions analysed were found to be homogeneous: 87.5% were heterogeneous, with from 2 to 14 different protein patterns.In total 202 different protein phenotypes (lines, biotypes) were detected. Together 13 HMW-GS alleles were detected at all three Glu-1 loci. The most frequent, at relevant loci, were alleles null, 7+9 and 5+10. More than 10% of protein, phenotypes reached a maximal value Glu-score.
