Principal component analysis of traits measured in the synthetic hexaploid wheat derived lines under normal (a) and water stress (b) conditions. Horizontal and vertical axes are the first and second principal components, respectively. DHE, days to heading; DF, days to flowering; RWC (%), relative water content; PHT (cm), plant height; AL (cm), awn length; SL (cm), spike length; PL (cm), peduncle length; SD, stem diameter (mm); YLD (g/m²), grain yield; SM, spike per m²; TGW (g), thousand-grain weight; GS, grains per spike; He, hectoliter (kg/he); BY (g/m²), biological yield; HI (%), harvest index; STI, stress tolerance index; YSI, yield stability index; CSI, combination of significant indices. The Number of genotypes is according to the first column (Genotype code) in table S3.
