METHOD: Visual Examination METHOD NARR: Detached leaves of each genotype were placed in petri dishes and inoculated with the 2 races of the fungus. Presence or absence of lesions was scored for each leaflet. RESULTS NARR: Thee GH compared to those of detached leaves in the laboratory, showed an unacceptable degree of discrepancy. Mcd was the species with the highest number of resistant clones. The results were accession dependent for chc but no the non-virulent race in the lab was accession dependent for mcd but not chc or cmm. AUTHOR EXPLANATION: The results obtained provide evidence of vertical resistance in some clones of cmm, mcd and chc.
