Table 2. Correlation coefficients between mean values of NAM RILs for lesion mimic traits and disease resistance score values obtained from previous studies (SLB, Kump et al. [34]; NLB, Poland et al. [35]; GLS, Benson [33]).
Traits | Scores on NAM populations (n<3606) | ||
HTR | SWR | DTAR | |
LESinv | 0.85**** (n = 3576) | 0.80**** (n = 3576) | 0.65**** (n = 3576) |
HTR | 0.84**** (n = 3581) | 0.70**** (n = 3582) | |
SWR | 0.60**** (n = 3580) |
LES, lesion score; HTR, height ratio; SWR, stalk width ratio; DTAR, days to anthesis ratio; SLB, southern leaf blight resistance score ; GLS, gray leaf spot resistance score; NLB, northern leaf blight resistance score; N, sample size and inv indicates that the original lesion/disease rating scale was inverted so that the correlation sign was consistent between comparisons so that in every case, a positive correlation implies increased HR was correlated with increased HR or with increased disease resistance. Significance of correlation coefficients (r);
