Assessment of Eight Faba Bean (Vicia faba L.) Cultivars for Drought Stress Tolerance through Molecular, Morphological, and Physiochemical Parameters

Determining and improving drought-tolerant cultivars is a major goal of plant breeding to face climate change. The productivity faba bean in Egypt affected by abiotic stresses, especially drought stress. This study evaluated eight Egyptian for tolerance under three soil water regimes consisting well-watered (100% field capacity), moderate stress (50% severe (25% capacity) pots greenhouse conditions using biochemical, physiochemical, molecular parameters. Nubariya 1, 3, Giza 716 showed the highest proline content values 50% capacity conditions, with 4.94, 4.39, 4.26 mmol/g fresh weights, respectively. On other hand, Sakha 4, 3 exhibited contents (7.8, 7.53, 6.17, 6.25, respectively) 25% treatment. profiling was conducted SCoT SRAP approaches. Fresh leaves were utilized extract DNA, ten primers six used PCR procedures. SRAP-PCR generated 72 loci, which, 55 polymorphic, 17 monomorphic. each had 48 24 total average polymorphism (%) achieved via 70.93% 80%, Based on profiles, cluster analysis identified clusters. first comprised cultivars; second included Akba 3300 third two 1 Nubariya3. According study’s findings, are remarkable parents developing genotypes. Additionally, this concluded that markers recreated trustworthy banding profiles evaluate genetic among cultivars, which regarded as cornerstone improvements crops.
