Fig 5. Heat susceptibility index (HSI) for physiological, yield and yield traits of wheat chromosome translocation lines and cultivars.
The horizontal lines classified genotypes into highly tolerant (HSI ≤ 0.5), tolerant (0.5 < HSI ≤ 0.75), moderately tolerant (0.75 < HSI ≤ 1.0), and highly susceptible (> 1.0) to high temperature stress.
