According to the Fisher’s LSD test, means followed by the same letter are not significantly different at p<0.05, ns= not significant, F tests (p<0.05) (F), Probability (p). In the current study, isolates F2, F35, F27 and F43 were reanalyzed on Cham1 and Cham6, however, disease reaction for the four isolates was analyzed previously and presented by Sakr [8].
