20.500.12556/DiRROS-23977 Adapted and yet evolving Long-term agronomic, nutritional and genetic assessment of the buckwheat variety Čebelica (Fagopyrum esculentum Moench) under Central European conditions Common buckwheat is valued for its adaptability, nutritional quality and potential to enhance sustainable cropping systems. However, yield instability and limited data on long-term genetic and nutritional stability remain key challenges. To address this, we conducted a nine-year field study (2012–2020) of the Slovenian variety Čebelica under Central European conditions, integrating agronomic, environmental, nutritional and genetic analyses. Grain yields varied widely (498.8–1418.0 kg ha−1), primarily due to climatic differences, with the precipitation as the dominant factor (F = 4.324, P = 0.027). Crop rotation explained 39.9 % of yield variation, with highest productivity following oats, maize or red clover. In contrast, protein (10.1–12.5 %) and fat (2.6–3.2 %) contents were highly stable (CV < 6 %), indicating robust physiological regulation. Micro-nutrient trends showed increasing iron and zinc, and decreasing sodium. Redundancy analysis revealed that precipitation, soil phosphorus and solar radiation explained over 75 % of trait variation, highlighting complex environmental control. Solar radiation influenced a trade-off between protein/fat and total phenolic content, suggesting metabolic shifts under varying light. Genetic analysis using nine SSR loci showed high diversity (Ho = 0.863) and a significant genetic shift between 2014 and 2015. Principal coordinate analysis and Mantel test (r = 0.556, P = 0.005) confirmed temporal genetic structuring, indicating ongoing adaptation despite the use of a single variety. These findings demonstrate that Čebelica is a nutritionally stable yet genetically dynamic variety, well suited for climate-resilient agriculture. This work offers rare, long-term insights into the ecological, agronomic and genetic dynamics of an underutilised but valuable crop. common buckwheat grain yield stability buckwheat nutritional quality temporal genetic structure crop protein Fagopyrum esculentum Moench true false true Angleški jezik Slovenski jezik Neznano 2025-10-30 14:05:11 2025-10-30 14:05:11 2026-04-20 11:47:55 0000-00-00 00:00:00 2026 0 0 Nasl. z nasl. zaslona; Soavtorji: Mohamed Neji , Vladimir Meglič, Lovro Sinkovič; Opis vira z dne 30. 10. 2025; str. 1-11 [article no.] 127895 Vol. 172 2026 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2026-01-01 633.12 1873-7331 10.1016/j.eja.2025.127895 255446531 https://www.sciencedirect.com/science/article/pii/S1161030125003910?via%3Dihub 1 b2902596-f2a6-11f0-a15d-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=38298 RAZ_Pipan_Barbara_2026.pdf RAZ_Pipan_Barbara_2026.pdf 1 0D74ABCDF88F5264EDD5E529364926D2 3046c907e2b08802c811706d69675a6c48fcd6ce18f1fb870c4a7e48b8adda75 ded78869-bc8a-11f0-94a7-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=35721 Kmetijski inštitut Slovenije 0 0 0
