Resistance of some commercial winter wheat cultivars to Tilletia tritici

Abstract

This paper deals with the resistance of twenty commercial winter wheat cultivars to common bunt causal agent (Tilletia tritici). Significant differences among the cultivars concerning the infection percent were observed, as well as the differences in the level of commercial cultivars' resistance to T. tritici. Most of the studied cultivars belonged to susceptible categories, and just few of them to the resistant ones. Cultivar Lasta was classified as highly resistant during the both investigation years in Kragujevac, while in Leposavić Lasta and Tiha were classified as resistant. The other studied cultivars were more or less susceptible.

U radu je prikazana otpornost dvadeset komercijalnih sorti pšenice prema prouzrokovaču glavnice (Tillecia tritici). Utvrđeno je da postoje značajne razlike u procentu infekcije pojedinih sorata, kao i to da je otpornost komercijalnih sorata pšenice prema T. tritici različita. Većina ispitivanih sorata pripadala je osetljivim, a manji broj otpornim kategorijama. Vrlo otporna u obe godine proučavanja u Kragujevcu bila je sorta Lasta, a u lokalitetu Leposavić u kategoriji otpornih bile su sorte Lasta i Tiha. Ostale proučavane sorte su bile manje ili više osetljive.
