Fig. 3. — The principal component analysis of grain yield, its components, and related traits with first two principal components (PC1 and PC2) in non-stress (NS) (A, C) and water-deficit stress (WD) (B, D) during 2013 (A, B) and 2014 (C, D) DS. The traits marked inside the solid circle/ellipses contributed more to the variation explained by PC1 and those marked inside the dashed ellipses to PC2. DTF, days to flowering; DTM, days to maturity; GY, grain yield; HI, harvest index; NGDW, non-grain dry weight; PH, plant height; PN, panicles per m²; SP, spikelets per m²; SPP, spikelets per panicle; SS, seed set; TDW, total dry weight; TGW, thousand grain weight.
