a Integrated QTL name composed by the trait code followed by the LG number in which the QTL was mapped and a decimal if more than one integrated QTL is detected for the same trait in the same LG
b Linkage group and bin position of the nearest flanking marker to the highest LOD peak
c Maximum LOD peak in the integrated QTL
d Maximum phenotypic variation explained in the integrated QTL
e LOD peak position of the maximum LOD peak in the integrated QTL
f Nearest flanking marker to the maximum LOD peak in the integrated QTL
g Negative and positive values refer to CO354 and CO441 as the origin of the beneficial allele, respectively
h Negative values indicate that the heterozygotes are more resistant than the respective mean between the two homozygotes
i Mean of the distribution of quantitative trait associated with the CO354 genotype
l Mean of the distribution of quantitative trait associated with the CO441 genotype
m Mean of the distribution of quantitative trait associated with the heterozygote genotype. When no dominance was fitted mu_H correspond to the mean of the sum among the average of the two homozygotes
n Year, sowing time and inoculation technique in which the QTL was detected: 1 = 2011A; 2 = 2011B; 3 = 2012A; 4 = 2012B; F = side-needle inoculation; T = toothpick inoculation
