PATHOGENICITY OF SOIL-BORNE FUNGI – CAUSAL AGENTS OF WHEAT ROOT DISEASES
Abstract
Breeding of wheat cultivar resistant against root diseases is a difficult problem because the lack of evidence about nature of pathogenicity of soil-borne fungi –causal agents of these diseases and their interaction with host plant.
The aim of this research was to investigate the character of pathogenicity of Bipolaris sorokiniana, Fusarium spp. и Oculimacula spp. – causal agents of common root rot, Fusarium root rot and eyespot on wheat seedlings under the artificial inoculation with isolates B. sorokiniana, F. oxysporum, F. culmorum, O. acuformis and O. yallundae. It has been revealed that there is significant difference between isolates B. sorokiniana, F. culmorum and F. oxysporum in pathogenicity, which was confirmed by the assessment of root rot severity on inoculated seedlings. Under the artificial inoculation of wheat seedlings with isolates O. acuformis and O. yallundae the severity of eyespot depends significantly on wheat cultivar characteristics. Based on results of our experiments we also suggested the virulence characteristic in B. sorokiniana isolates.
Thus, it has been confirmed the specificity of interaction the soil-borne fungi with plant host in every particular pathosystem, that should be considered in breeding programs for resistance against root and stem-base diseases.
