20.500.12556/DiRROS-29040 Uncovering phenotypic variation in common bean (Phaseolus vulgaris L.) insights from the INCREASE project The common bean (Phaseolus vulgaris L.) is a major food legume and an important plant genetic resource for sustainable agriculture. Effective use of this diversity requires integrated evaluation of phenotypic variation and agronomic performance, with preliminary assessments of line performance across seasons. In this study, phenotypic diversity was evaluated in a subsample of the INCREASE R-core collection, a large and well-defined core set of common-bean SSD lines derived from heterogeneous germplasm lines. A total of 507 lines were characterized using 57 agro-morphological traits. Multivariate analyses revealed wide phenotypic diversity structured mainly by growth habit, phenology, and yield-related traits, with clear differentiation among lines. Mixed-data clustering identified cluster 4 as the main phenotypic group associated with higher seed- and yield-related performance and composed predominantly of indeterminate climbing landraces. Multi-trait selection indices generally ranked lines from this group highest, while early, small-seeded types tended to show lower overall performance. Evaluation of a selected subset of 19 lines across two growing seasons revealed marked year-to-year variation in yield performance, indicating contrasting responses among otherwise high-performing lines. The multi-trait genotype–ideotype distance index further distinguished lines with balanced performance across traits and years. Overall, this study shows that large-scale phenotypic characterization combined with multi-trait evaluation can provide a useful exploratory basis for identifying breeding-relevant ideotypes and promising lines for further validation for common-bean improvement. common bean phenotypic diversity germplasm evaluation multivariate analysis selection index year-to-year variation yield stability Phaseolus vulgaris true false true Angleški jezik Latinski jezik Neznano 2026-04-20 08:08:36 2026-04-20 08:08:37 2026-04-21 04:15:19 0000-00-00 00:00:00 2026 0 0 Soavtorji: Lovro Sinkovič, Roberto papa, Elena Bitocchi, Elisa Bellucci, Peter Dolničar, Barbara Pipan; Nasl. z nasl. zaslona; Opis vira z dne 20. 4. 2026; str. 1-27 iss. 8, [article no.] 1249 Vol. 15 2026 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2026-04-18 635 2223-7747 10.3390/plants15081249 275717379 RAZ_Tavakoli_Hasanaklou_Hourieh_2026.pdf RAZ_Tavakoli_Hasanaklou_Hourieh_2026.pdf 1 C4FDE2B977278664630E91D023C6FE6D 68dccd93ef814a3256b2599c099c41e81914ec37d551c0daad84c13634bce2ce 7ebab399-3c7f-11f1-b8c8-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=43362 Kmetijski inštitut Slovenije 0 0 0
