abstract = {One-flower vetch (Vicia articulata) was widely cultivated in the Mediterranean Basin in
the past but is currently underutilized. Valuable germplasm collections are stored in genebanks,
which are poorly characterized. In an attempt to explore adaptation of landraces we performed a
multi-environment field testing, showing the availability of valuable resources for crop development,
with average yield across environments ranging from 651 to 1102 kg/ha. Environmental factors and
significant Genotype-by-Environment (G*E) interaction hampers selection of superior genotypes.
Heritability-Adjusted Genotype plus Genotype-by-Environment interaction (HA-GGE) biplot
performed here allowed to focus on the G and G*E interaction components relevant to cultivar
evaluation. Landraces Va-38 and Va-85 were identified as the highest yielding landraces, being
also the most stable over the environments. Two additional groups of landraces with relatively
high yield were also identified but showing little stability across environments, with landraces
Va-91 and Va-103 performing better in Córdoba, whereas Va-1, Va-2 and Va-66, did in Escacena.
Córdoba appeared as a useful environment for selection, being representative, discriminant, and
reproducible. Differences in precocity among landraces had little effect on yield in any of the studied
environments. Temperature was the climatic factor most influential on yield as shown by Non-Metric
Multidimensional Scaling (NMDS) analysis. High temperatures after flowering being the most
limiting factor for yield. Increased radiation during and after flowering were beneficial, with rain
having little effect.},
