Özet
In this research, 13 out of 60 genotypes carried only gliadin band 42, while 16 genotypes possessed only gliadin band 45. Twenty-eight of remaining genotypes had both gliadin 42 and 45. Three genotypes carried neither gliadin band 42 nor gliadin band 45. When the genotypes examined with respect to glume color, 13 genotypes were classified as buff glumed. All these 13 genotypes had gliadin band 42. Of the 16 white-glumed, 15 genotypes had gliadin band 45 present. Only one genotype had gliadin band 42 present. We concluded that electrophoretic analysis in combination with glume color may be used in segregating populations, and such reliable markers should be evaluated with SDS-sedimentation test for developing to cooking quality in durum wheat breeding programs.
