20.500.12556/DiRROS-24983 Expression of Useful Traits in Determinant Buckwheat Accessions in the East of Ukraine Izražanje uporabnih lastnosti pri determinantnih rastlinah ajde na vzhodu Ukrajine The article presents results of studying a collection of determinant buckwheat (Fagopyrum esculentum Moench) genotypes in the East of Ukraine. The purpose of the study was to select highly productive and stress-resistant genotypes for breeding. We noted a considerable variability of biometric and agronomic characteristics between genotypes. The highest productivity (3.2 g/plant) was recorded for accession UC0101058 (UA) and the highest thousand-kernel weight (37.4 g) was recorded for accession UC0100286 (BY). There was a strong positive correlation between the number of kernels per plant and productivity (r = 0.93). Using multivariate statistics methods, we distinguished major clusters of genotypes. Promising accessions (UC0100167 (UA), UC0101058 (UA), and UC0102186 (UA)) were selected for further breeding. Using principal component (PC) biplot analysis, we evaluated genetic relationships between the studied accessions and genetically distant genotypes (UC0101058 (UA), UC0100286 (BY), and UC0100963 (UA)) were identified as potential outliers. V članku so predstavljeni rezultati proučevanja zbirke determinantnih genotipov ajde (Fagopyrum esculentum Moench) na vzhodu Ukrajine. Namen študije je bil izbrati visoko produktivne in na stres odporne genotipe za žlahtnjenje. Opazili smo precejšnjo variabilnost biometričnih in agronomskih lastnosti med genotipi. Najvišja produktivnost (3,2 g/rastlino) je bila ugotovljena za vzorec UC0101058 (UA), največja teža tisoč zrn (37,4 g) pa za vzorec UC0100286 (BY). Obstajala je močna pozitivna korelacija med številom semen na rastlino in produktivnostjo (r = 0,93). Z multivariantnimi statističnimi metodami smo razločili glavne skupine genotipov. Za nadaljnje žlahtnjenje so bili izbrani obetavni vzorci (UC0100167 (UA), UC0101058 (UA) in UC0102186 (UA)). Z dvoplotno analizo glavne komponente (PC) smo ovrednotili genetske odnose med proučevanimi akcesijami in genetsko oddaljenimi genotipi (UC0101058 (UA), UC0100286 (BY) in UC0100963 (UA)), ki so bili identificirani kot potencialno izstopajoči. buckwheat determinant collection breeding productivity development true false true Angleški jezik Slovenski jezik Avtorske pravice (c) 2025 Fagopyrum Članek v reviji 2026-01-07 09:20:25 2026-01-07 09:20:25 2026-03-04 10:06:24 0000-00-00 00:00:00 2025 0 0 Nasl. z nasl. zaslona; Opis vira z dne 14. 5. 2025 str. 5-17 št. 1 letn. 42 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2025-03-24 633.12(477) 2712-2859 10.3986/fag0044 235888387 https://ojs.sazu.si/fagopyrum/article/view/8064 0 e59a12d4-ed30-11f0-94a7-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=37693 _Fagopyrum_vol+42-1_2025_article+Chuiku+Trayhub_web.pdf _Fagopyrum_vol+42-1_2025_article+Chuiku+Trayhub_web.pdf 1 15F86E17724F26C21000594897731EEC 9987e3411ca0e11388533cd32e3e4cb2b4121d132867f1bed6016756c2cf81f8 3cf2c455-eba3-11f0-94a7-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=37445 Slovenska akademija znanosti in umetnosti Fagopyrum [Elektronski vir] 0 0 0
