For both traits, the QTL analysis was performed over three different seasons with and without intragenic VvAGL11 markers. The table shows the closest marker to the peak in the LOD profile, the LOD value for the same marker (LOD), the 1-LOD support confidence interval (CI), the proportion of phenotypic variance explained by QTLs with parametric and non-parametric analysis (Var. Expl. MQM and Var. Expl. K-W respectively), the P-value for the Kruskal-Wallis test (P), and the mean seed fresh weight or berry weight values for genotypic classes (aa, ab and bb,) detected in the RS × S progeny.
