Research Abstract

The differentiation of physiological races in Fusarium graminearum Schwabe, a causal fungus of scab disease was analyzed in this study.
A total of 110 Fusarium strains was inoculated onto ten barley and 15 wheat varieties separately by 'cut-spike' inoculation method. Percentage of infected florets (barley) and spikelets (wheat) was recorded and it was transformed into the degree of angle for the statistical analyzes.
Both barley variety x strain and wheat variety x strain interactions were not remarkable and the correlation coefficients among host varieties were more than 0.8, suggesting that the gene-for-gene differentiation within species was not significant.
On the other hand, the variance analysis and the principal component analysis revealed that interaction between strain x host species i.e.barley and wheat is statistically significant. Whereas the correlation coefficients among host species were as high as 0.8. Therefore the pathogenicity of Fusarium strains differentiated slightly against the different host species, barley and wheat.
