The present investigation was carried out to determine genetic variability and the estimate of genetic parameters for agro-physiological charactristics in bread wheat genotypes. The results of analysis of variance (ANOVA) showed significant difference (p<0.01) for flag leaf area (FLA), relative water content (RWC), evaporate transpiration efficiency (ETE), water use efficiency (WUE), chlorophyll a (Chla), chlorophyll b (Chlb), total chlorophyll (Chlt) and grain yield per spike (GY/S). The highest estimate of broad sense heritability was recorded for GY/S, WUE, Chl a, Chla/b, Chl b, RWC, and ETE (>80%). The characters GY/S and WUE exhibited high broadsense heritability (h2bs) coupled with high genetic gain indicating that these traits can be further improved through individual plant selection. High positive co-heritability was observed between stomatal conductance (SC) and ETE (714.3), whereas high negative co-heritability was observed between relative water loss (RWL) and Cha/b (-466.7).
