Table 5 Correlation coefficients between grain yield under normal and heat stress conditions and heat tolerance indices of Lentil genotypes. The stress indices STI, MRP, MP, YI, GMP, and HM showed significant positive correlation with both Yp and Ys, indicating their usefulness in identifying high-yielding genotypes. 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. NSP > 0.05; * P ≤ 0.05; ** P ≤ 0.01, ***p ≤ 0.001.
