Sažetak
U radu je ispitivana ekološka stabilnost visine biljke kod jedanaest divergentnih sorata pšenice iz različitih geografskih regiona gajenja u tri vegetacione sezone. Parametri stabilnosti su izračunati primenom modela Eberhart i Russell (1966). Prema koeficijentu regresije, sve sorte su pokazale zadovoljavajuću stabilnost za ispitivano svojstvo. Kao najstabilnije, za visinu biljke, su se pokazale sorte NS Rana 2, Manitou i Lovrin 21, dok je najnestabilniji genotip bio Peking 11.
Abstract
Ecological stability of plant height for eleven different wheat varieties originated from distant geographical growth regions, in three vegetation periods were studied in this paper. Stability parameters were calculated using the model of Eberhart and Russel (1966). According to regression coefficient, all studied varieties showed stability on satisfactory level for plant height. The most stable, for plant height, appeared to be varieties NS Rana 2, Manitou and Lovrin 21, while the unstable genotype was Peking 11.
