Genotype x Environment Interaction and Stability Analysis of Some Narbonne Vetch (Vicia narbonensis L.) Genotypes

The objectives of this research are to determine genotype x environment interactions and stability of seed yield and some plant characters of
Narbonne vetch (Vicia narbonensis L). Thirteen Narbonne vetch genotypes were grown at two different locations during 2000-2002 years. This research was
carried out as randomised completed block design with three replications. Significant differences were found (P≤0.01) among Narbonne vetch genotypes for
plant height (57.54-77.98 cm), pod number per plant (10.97-20.09), and seed yield per plant (7.22-22.64 g). Genotype x environment interaction was found to
be significant (P≤ 0.01) in all investigated characters. Mean values of genotypes (x), regression coefficient (b) and deviation from regression (S2d) were i
evaluated as stability parameters. According to stability analyses, genotype 133 and 600 showed upper performance about seed yield per plant in two
locations. On the other hand, genotypes I would recommend for suitable locations which were loamy and limy soils and rainy and cool season climatic
conditions.
