ESTERASE ISOZYMES IN CANADIAN BARLEY CULTIVARS

Abstract
Fifty-five currently licensed Canadian cultivars and some parental genotypes were analyzed by starch-gel electrophoresis for esterase isozyme patterns and extent of polymorphism for these isozymes. Each cultivar was assigned to one of nine different patterns observed. Fifty-one percent (28) of the cultivars exhibited polymorphic isozyme patterns. The polymorphism was a varietal characteristic and apparently not associated with the age of the cultivar or area of adaptability.
