Stability of Vicia faba L. cultivars and responsible traits for Aphis fabae Scopoli, 1763 preference

The study aimed to evaluate the responsible traits of preference Aphis fabae Vicia faba cultivars and their stability in multi-environment field tests. experiment was carried out at Institute Forage Crops (Pleven) during period 2016 2018. Aphid infestation assessed by recording number per plant pod formation, while chemical composition determined standard Weende system methods. Canonical correspondence analysis showed that aphid density negatively correlated with amount rainfall humidity until aphids were positively temperature. According GGE biplot cultivar Fb 3270, followed BGE 029055 002106 stable a low defined as tolerant. A significant negative correlation found between height (r = -0.447). protein content positive 0,686), phosphorus cyanogenic glycoside concentration significantly incidence -0.411, r -0.685, respectively). results lay groundwork for further analyses finely dissect A. tolerance V. pave way development methods predict ...
