Summary of genome associations for well-watered and water deficit conditions.

Variable, QTL name, chromosome (Chr), position, its significance, phenotypic variance explains by QTL (R2 (%)), SNP alleles, frequency (MFA) and direction of effect and gene annotation where the QTL resides. Relative chlorophyll content (CC), well-watered condition (WW), maximum quantum efficiency of PSII (FvFm), tuber number (TN), water deficit condition (WD), sucrose (Suc), Glucose (Glc), fructose (Fru), relative water content (RWC) and tuber fresh weight per plant (TW).
