Fig. 8

Root system architecture of Swarna, Moroberekan and the four selected QTL lines in a gel imaging system. Seedlings were grown in control (C: Yoshida) and water deficit (WD: Yoshida + 10% PEG) treatments and imaged at 15 days after germination for RSA analysis (a). Results of percent change in maximum number of roots (MNR) as compared to Swarna are presented (b). Bars represents mean values ± se (n = 26 for Swarna and Moroberekan, and n = 8–12 for the QTL lines) and letters indicate difference significance groups
