Table 2 Mapped integrated QTLs for Fusarium ear rot (FER), fumonisin B1 (FB1) contamination and days to silking (DTS) by multiple QTL mapping in a F2:3 population (CO441xCO354) artificially infected with side-needle (F) and toothpick (T) inoculation methods in early (A) and late sowing (B) of 2011 and 2012, detected in more than 1 year/sowing/inoculation technique. Co-mapping QTLs for FER, FB1 contamination and DTS are in bold

  1. 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
  2. b Linkage group and bin position of the nearest flanking marker to the highest LOD peak
  3. c Maximum LOD peak in the integrated QTL
  4. d Maximum phenotypic variation explained in the integrated QTL
  5. e LOD peak position of the maximum LOD peak in the integrated QTL
  6. f Nearest flanking marker to the maximum LOD peak in the integrated QTL
  7. g Negative and positive values refer to CO354 and CO441 as the origin of the beneficial allele, respectively
  8. h Negative values indicate that the heterozygotes are more resistant than the respective mean between the two homozygotes
  9. i Mean of the distribution of quantitative trait associated with the CO354 genotype
  10. l Mean of the distribution of quantitative trait associated with the CO441 genotype
  11. 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
  12. 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
