MLN severity scores taken on a scale of 1–9, where 1–4 is resistant to moderate resistant. MLN1, 1st score of MLN severity taken 21 days from date of first inoculation; MLN2, 2nd score of MLN severity taken 7 days after the first score; MLN3, 3rd score of MLN severity recorded 14 days after the first score; MNL4, 4th score of MLN severity taken 21 days from the first score; AUDPC, area under disease progress curve calculated from the four MLN scores; LSD (0.05), Fisher’s protected least significant difference at 5% level; and CV%, coefficient of variability measures in percent.
