Chickpea (Cicer arietinum L.) is an important legume, valued for its nutritional and bioactive components. In this study, seven chickpea advanced breeding lines, an elite line, and a cultivar were evaluated under field conditions to assess superior agronomic performance, seed quality traits, nutritional composition, and phenolic profile. A combined approach was used, integrating field phenotyping, seed quality assays, and LC–MS-based phenolic profiling. Significant genotype-dependent variation was observed in plant height, biomass yield, and 1000-seed weight, with P9/14 and P10/14 advanced lines performing strongly in yield-related traits. Seed functional properties also differed, with P8/14 showing superior hydration and seed coat characteristics, while cv. Blanco Sinaloa exhibited the highest hydration and swelling capacities. Protein content ranged from 22.6% to 25.4%, with P9/14 being the most protein-rich advanced line. Phytochemical and antioxidant analyses revealed substantial differences among genotypes: Blanco Sinaloa and M-15370 showed the highest total phenolics and ABTS activity, whereas P14/14 exhibited the strongest DPPH scavenging capacity. LC–MS profiling identified six major phenolic subclasses, with isoflavones predominating and biochanin A and its derivatives being the most abundant compounds. Overall, the integration of agronomic, nutritional, and phytochemical data highlights the advanced lines P14/14 and P9/14 as promising candidates for future breeding programs aimed at enhancing chickpea nutritional quality and functional seed attributes.
