Otpornost novih linija ječma prema prouzrokovaču lisne rđe

Abstract

U radu je prikazana otpornost novih linija ječma, koje su prijavljene Komisiji za priznavanje poljoprivrednog bilja, prema Puccinia hordei. Utvrđeno je da je većina ispitivanih linija osetljiva prema ovom parazitu, ali da postoje i otporne. Prosečan koeficijent infekcije u 1995. godini je bio veći kod jarih, a u 1996. godini kod ozimih linija.

The barley leaf rust, caused by biotrophic fungus Puccinia hordei Otth., is one of the most important disease in Yugoslavia. In this paper resistance of 14 winter and 12 spring barley new lines in J 995, and 18 winter and 16 spring lines in 1996 was investigated. The obtained results demonstrated that most of the barley lines were susceptible to leaf rust, but some of them were resistant. The mean coefficient of infection in 1995 were higher on spring and in 1996 on winter barley lines.
