Abstract

The protein diversity of 45 genotypes (forty genotypes selected within two gene pools and five varieties) of meadow fescue was examined. Genetic variation was described using ISTA/UPOV methods for crop variety identification. Modifications of acid-PAGE of alcohol-soluble proteins (prolamins), and SDS-PAGE of salt-soluble proteins (globulins) were elaborated for seed analyses of <I>Festuca pratensis </I>Huds. The results of this study indicated that the genotypes of meadow fescue could effectively be differentiated on the basis of polymorphism, detected between protein patterns. SDS-PAGE presented a higher differentiation power and better repeatability; thus could be used as a rapid and reliable method for the identification of <I>F. pratensis </I>genotypes in breeding programmes and the seed industry.
