METHOD: Visual Examination CONDITIONS: Growth Chamber - 12h light, at 16C METHOD NARR: Plants were spray inoculated at about 6 weeks old. Race O and race 1.3.4.5 were each applied and evaluated seperately. Five days after inocuscored visually for percent necrotic tissue. Plants on which all the leaves were dead but having no stem lesions were rated as 70% necrotic. RESULTS NARR: Tbr was considered resistant while brd was sensitive. AUTHOR EXPL was generated and tested for resistance similarly to the parents. All of the progeny were significantly less necrotic than the brd parent for both races tested. However, the % necrosis was higher overall with race 1.3.4.5.
