Sažetak
The aim of this investigation was to determine the reliability of a method of artificial spike inoculation compared with natural infection data and to determine differences in resistance of the Bc winter wheat lines to Fusarium head blight in two climatically different years. Two identical small-scale trials were conducted with 15 Bc winter wheat lines and three sources of resistance: Poncheau, (D48 x 42 x 6) 2 and Roazon in five replications planted in Botinec in 2001 and 2002. The first trial was conducted under natural infection, and the second was inoculated with a spore suspension of 5 x 105 spores/ml using a hand sprayer. Correlation coefficient was determined for resistance in natural and artificial conditions (r = 0.78 and 0.82). Artificial inoculation of wheat spikes with Fusarium graminearum spore suspension using the sprayer method was successful in different weather conditions. Sources of resistance Poncheau, (D 48 x 42 x 6) 2 and Roazon proved their value. Bc winter wheat lines Bc 5792, Bc 733, Bc 5887, Bc 18, and Bc 5210 were found to reveal higher resistance to Fusarium head blight.
