Table 5 SNP markers significantly associated (−log10(p) ≥ 3) with yellow index identified by GWAS (model MLM + K + PCs) in the whole tetraploid wheat collection and in the durum sub-population evaluated in six environments (F09, V10, V12, F12, V13, V14)

  1. - = not significant
  2. R2 = Phenotypic variation explained by the QTL (%)
  3. Chromosome and map position from Maccaferri [29] and -log10(p) values are reported for each marker in each environment and in the mean of the environments. Phenotypic variation (R2) and additive effect are reported only for markers significant in the mean of all six environments
