Correlation coefficient “r” between selected traits and relative trait change index (RTC) for wheat genotypes grown in root-box and root-basket containers. Plant height (H); leaf number (L_No); dry matter of shoot (S); total root dry matter (R); total plant dry matter (S+R); shoot-to-root ratio (S/R); number of nodal roots (R_No); length of nodal roots (R_L); mean root length (R_ML); (df = 4).
