Pathogenicity of Fusarium crookwellense Burgess, Nelson and Toussoun to 12 genotypes of oat (Avena sativa l.).

Abstract

Within the years 2002-2004 12 genotypes of oat (Bachmat, Budrys, Bohun, Chwat, Cwał, Deresz, Hetman, Rajtar, Sam, Szakal, STH 5501, STH 5601) were examined to determine their susceptibility to Fusarium crookwellense. The examination was led under field conditions of Zamość region (south - eastern part of Poland),. Both oat grains and soil were inoculated with Fusarium crookwellense nr 47, what caused a reduction in numbers of seedlings - from 24.6% (cv. Bohun) to 52.9% (cv. Sam); plants before harvest - from 11.6 (cv. Bohun) to 68% (cv. Sam)..
