Correlation matrix for growth characters of cacao progenies, obtained from complete diallel crosses, under drought condition (predawn ΨWL between –2.0 to –2.5 MPa).

SD = stem diameter (mm); TLA = total leaf area per plant (m2 x 10−4); RB = root biomass (g); SB = stem dry biomass (g); LB = leaf dry biomass (g); TB = total dry biomass (g); RL = root length (mm); RD = root mean diameter for second order branches (mm); RV = root volume (cm3); RD[<1 mm] = fine roots length (cm cm-3); RD[1-2mm] = medium roots length (cm cm-3).
