(B) ATF188 base population vs. cycles of selection for deep root production. (C) ATF192 base population vs. cycles of selection for deep root production. Different letters indicate a significant difference at P 0.05 using Fisher's protected least significant difference mean separation. Connecting lines indicate the selection cycles over which the total percentage gain in each panel was calculated.
