A field experiment was conducted during the 2023–2024 growing season at the University of Mosul Research Station to evaluate the performance of thirteen genetic combinations of (vicia faba L.) Under supplementary irrigation conditions, it was designed (RCBD) with three replicates.

Analysis of variance showed highly statistically significant differences (P ≤ 0.01) between genotypes for all quantitative traits studied. Genotype (4: FLIP17-065FB) recorded the highest significant values for plant height (149.70 cm), pod length (12.40 cm), green biological yield (4064.00 g plant⁻¹), and green pod yield (1268.00 g plant⁻¹).

The number of seeds / pods and weight of 100 seeds showed the highest Broad-sense heritability (0.966 and 0.963, respectively), along with high expected genetic advance (41.91 percent and 48.57 percent, respectively), This demonstrates the predominance of additive gene action and the potential efficiency of direct selection to improve these traits. Correlation analysis revealed positive genetic correlations between plant height, seeds per pod, and green pod yield. Genotypes (4: FLIP17-065FB), (11: FLIP17-078FB) and (5: FLIP17-066FB) showed potential as parental lines for improving bean productivity under supplementary irrigation.
