The mean values were taken from 5 replicates with 7–10 seedlings for each replicate. The total number of seedlings showing symptoms was 277, with an average of 52.83 seedlings per accession. Mean values of the recorded responses followed by different letters were significantly different for each recorded characteristic based on Tukey's Studentized Range (HSD) test at p < 0.05
