Abstract
Systemic movement of Pyrenophora graminea in five barley genotypes was used to quantify the infection level of leaf stripe disease. The systemic movement of the fungus was slower in the resistant than in the susceptible genotypes and enabled easy differentiation among them. Significant correlations were found (P = 0.001) between relative in vitro value and both percentage yield loss (r = 0.94) and disease incidence (r = 0.97) obtained from the field experiment. P. graminea movement within barley plants can be a useful criterion when differentiating resistant from susceptible genotypes.
