Growth and development of narbon vetch (Vicia narbonensis L.) genotypes in the semi-arid central Turkey

Abstract

In order to investigate the growth and yield potential of narbon vetch (Vicia narbonensis L.), to elucidate the possible associations of plant traits, to inquire the basics of responses shown by genotypes across years through examining of genotype × year interaction effect, and to extrapolate the nature of adaptation, 27 accessions were evaluated for yield and yield related characters over four subsequent cropping seasons in the central Turkey. Days to harvest, biomass, seed yield, and harvest index were measured, and the results were analyzed by multiple statistical procedures: principal component analysis, linear regression analysis, cluster analysis, descriptive statistics, analysis of variance and additive and multiplicative model analysis. Four year effects were grouped into three classes (good, fairly-good and poor). Seed yield was positively correlated with days to harvest in the first (p < 0.05) and fourth (p < 0.001) years, and with biomass in all years, which made them plastic and fixed traits respectively. For seed yield, the 27 genotypes were separated into four groups, and year and interaction effects were found to be highly significant (p < 0.001). Certain genotypes behaved differently; G25 and G11 were more suitable for specific adaptation, while G2, G4, G6 and G27 were best for broad adaptation. These selected genotypes could be used as a set of reference lines in the evaluation of narbon vetch germplasm for better yield and adaptation. The enhanced developmental flexibility through adjusting plant growth-longevity combined well with higher biomass and harvest index is the primary form of narbon vetch adaptation to the semi-arid central Turkey and similar environments in the Mediterranean area.Additional key words: AMMI model; biomass; days-to-harvest; harvest index; seed yield; specific and broad adaptation.

Se midieron los días a cosecha, la biomasa, rendimiento de semillas e índice de cosecha. Los resultados se analizaron por varios procedimientos estadísticos: análisis de componentes principales, análisis de regresión lineal, análisis de grupos, estadística descriptiva, análisis de varianza y AMMI. Los efectos de los 4 años se agruparon en tres clases (buenos, bastante buenos y malos). El rendimiento de

“…The species is also of great importance in crop rotation systems, either as pure stands or in a mixture with cereals for fresh forage or hay to provide high quality livestock feed (Altınok 2002;Altınok & Hakyemez 2002;Iptaş & Karadağ 2009;Nizam et al 2011). Furthermore, narbon vetch is a valuable green manure plant due to high green biomass production, and as a legume, its ability to fix large amounts of nitrogen to the soil (Albayrak et al 2004a;Albayrak et al 2004b;Avcıoğlu et al 2009;Fırıncıoğlu et al 2012).…”
