EMS-induced mutagenesis in Choy sum (Brassica chinensis var. parachinensis) and selection for low light tolerance using abiotic stress indices

Table 3 Pearson correlation coefficient (r) between different stress indices of EMS induced five M3 Choy Sum mutants. SSI, stress susceptibility index; RSI, relative stress index; TOL, tolerance index; MP, mean productivity; STI, stress tolerance index; GMP, geometric mean productivity; YSI, yield stability index; SRI, stress response index; ATI, abiotic tolerance index estimated from leaf yield under light and shade condition
