METHOD: Visual Examination CONDITIONS: Green House METHOD NARR: A number of variables were tested to find the most effective method of inoculation. The most effective involved crushing the leaf and petiole with a forceps and thek old seedlings with bacterial suspension. Seedlings were maintained in a mist chamber at 20C before and after inoculation. In the first screening, utilizing three subspecies of Erwinia, disease severity was recorded as per In the second screening, only Ecc was used to inoculated and disease severity was ranked 0-4. The disease index for different accessions was calculated as a mean value for all inoculated seedlings. Seedlings were also inoculstant strain of Ecc SR 394 to determine external and internal survival of the bacteria by dilution plating. RESULTS NARR: In resistant lines, disease severity was often very low even when extremely high levels of bacteria are used. in a given symptomless vs diseased plant were apparently not directly correlated with disease severity. AUTHOR EXPLANATION: These seedling results may not accurately reflect resistance in older plants.
