LPI, length of penultimate internode; PH, plant height; n.s., not significant; *P < 0.05, **P < 0.01 and ***P < 0.001; PVE, phenotypic variation explained. The environments were at Changping (CP) and Shunyi (SY) under well-watered (WW), drought-stressed (DS) and/or heat-stress (HS) conditions in 2010–2012.
