Maximal root lengths of 26 IK-CSSLs, IR64, and Kinandang Patong (KP) grown in hydroponic conditions. Maximal root lengths of 26 IK-CSSLs, IR64, and Kinandang Patong (KP) grown in hydroponic conditions. Values are given as mean ± SD (n = 24). Black and gray bars indicate lines with longer and shorter roots, respectively, than those of IR64 (P < 0.001, Dunnett’s test). Dashed lines show the mean values of IR64. Substituted chromosome in each line is indicated at the bottom. (A) First trial (data at 9 d after germination). (B) Second trial (data at 8 d after germination). Yuka Kitomi et al.
