Examined traits are: plant DW, leaf area, lateral root (Lat.) length, axile root (Ax.) length, leaf area/root length ratio (Lf/Rt), and the portion of the primary root
length on the embryonic root system (Pr. port.).*, ***: comparison of line mean values significant at P≤0.05 and 0.001, respectively, ns = not significant.
