  1. FLL flag leaf length, FLW flag leaf width, FLWR flag leaf length to width ratio, FLA flag leaf area, BAFL basal angle of flag leaf. E1 to E4 represent the location at Yongdeng (103°18’ E, 36°42’ N), Gansu, China, in 2011and 2012, at Anning (103°51’ E, 36°04’ N), Gansu, China, in 2012, and at Yuzhong (104°07’ E, 35°51’ N), Gansu, China, in 2013, respectively. Correlation coefficients in the lower left segment apply to the DS, and those at the upper right part are for WW conditions; *and **significant at 0.05 and 0.01 level, respectively
