Table 3.
Leaf area index (LAI), cumulative actual evapotranspiration (ETa), mean grain yield (GY, kg·ha−1), cumulative evapotranspiration during grain filling (ETa GF), and the vegetative stages (ETa VEG) and water productivity (WP) for the twenty-two wheat varieties grown for two years and under two water regimes. Broad-sense heritability (H2) is shown for the mean comparison. Pearson’s correlation coefficient (Correlation P GY) of ETa GF, ETa VEG, and WP with grain yield) is also shown.
