Correlation matrix demonstrating the correlations among yields under normal and stress conditions and heat tolerance indices. Correlation coefficients are depicted as the colour and size of the circles. Yp yield under normal conditions, Ys yield under stress conditions, TOL tolerance index, STI stress tolerance index, SSPI stress susceptibility percentage index, YI yield index, YSI yield stability index, RSI relative stress index, MP mean productivity, GMP geometric mean productivity, HM harmonic mean, MRP mean relative performance, PYR percent yield reduction.
