This paper attempts to evaluate the banding patternsof non-gluten protein isolates from the grain of durum wheat varieties. Underreduced condition, polyacrylamide-gel electrophoresis has revealed a number ofdifferent sized albumin and globulin protein bands. The electrophoretic patternof globulin showed more polymorphisms than that of albumin. High polymorphism,both in band intensity and occurrence, was observed between 15 kDa and 35 kDa.Most of the protein bands were scored in the range of 10 kDa and 85 kDa in thetwo protein fractions. At a cutoff point 2.5, cluster analysis based on theSDS-PAGE of globulin proteins classified the durum wheat varieties into threemajor family groups. Generally, the experiment showed the suitability andusefulness of globulin protein fractions as a genetic marker in discriminatingdurum wheat genotypes.
