Disease development and yield loss due to the net blotch pathogen (Pyrenophora teres f. teres) were investigated in two barley genotypes, UC 603 and Kombar. These genotypes show moderately high to high (moderately susceptible to susceptible) infection responses (based on lesion size and degree of associated chlorosis) to P. t. f. teres in both the seedling (growth chamber study) and adult plant (field study) stages, but disease development is much reduced on UC 603 in the field(.)
