  1. The phenotypic data for each trait is the mean averaged across three experimental sites under drought-stressed (DS) and well-watered (WW) conditions at Anning farm station, Gansu, China (103°51′E, 36°04′N, 1600 m ASL) in 2012–2013 (E1), at Yongdeng farm station, Gansu, China (103°18′E, 36°42′N, 1950 m ASL) in 2013–2014 (E2), and at Yuzhong farm station, Gansu, China (104°07′E, 35°51′N, 1900 m ASL) in 2014–2015 (E3). The asterisks in the column of “parent Q9086” represent significant differences in phenotypic data between two parents by the F test. The asterisks in the columns of “mean” and “CV (%)” represent significant differences in phenotypic data between two water conditions by the F test. *P < 0.05, **P < 0.01.
