METHOD: Visual Examination CONDITIONS: Green House METHOD NARR: High humidity was maintained in the GH. Two experiments were carried out. In the first experiment, all clones were used, in the second clones were chosen for resislier test. First symptoms were observed 7 days after inoculation and readings wre taken 12 days after inoculation. Presence or absence of lesions was scored for each plant. RESULTS NARR: The results obtained in the GH coaves 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 not cmm or mcd. The reaction to the non-v 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.
