Evaluation and characterization of resistance to fusarium head blight caused by Fusarium culmorum in UK winter wheat cultivars

Progression of deoxynivalenol (DON) concentrations in spikes and kernels was studied in relation to Fusarium head blight (FHB) symptoms in five winter wheat cultivars, differing in resistance to FHB, after single floret inoculation with an aggressive isolate of Fusarium culmorum. After inoculation in field conditions the spikes were detached from the plant and kept in the greenhouse under controlled conditions. High concentrations of DON were detected in susceptible cultivars at an early stage of pathogenesis (7 days after inoculation). Over the whole examined 21-day period and also at maturity spikes contained more DON than kernels. While differences between cultivars in the accumulation of DON were highly expressed already 7 days after inoculation, differences in symptomatic reactions were not clear until day 21. Owing to the reported crucial role of DON at early stages of pathogenesis, the importance of appropriate timing of fungicide application is highly stressed.

AbstractToxin B — trichothecene deoxynivalenol (DON) is the most frequent Fusarium mycotoxin in Fusarium head blight (FHB) disease produced by Fusarium fungi. Thirty-one samples of naturally cultivated winter wheat were collected from different localities in Slovakia and evaluated for DON content, and after an artificial inoculation twelve of winter wheat cultivars were evaluated for FHB, fusarium damaged kernels (FDK) and DON content (resistance Type I and II) during two years. Plants were inoculated at anthesis with a conidial suspension of Fusarium culmorum (W. G. Smith) Sacc. The highest mean contents of DON 1.641 ppm were found in produced potato region (PPR) and 1.654 ppm in produced sugar beet region (PSBR). A positive correlation was found between DON content and rainfall, and a negative correlation was found between content of DON and temperature. Lower positive correlations were found between the contents of DON in 2003 and 2004 in the resistance Type I and Type II in twelve artificially infected cultivars. The significant positive correlations in content of DON were found between resistance Type I and Type II in the years 2003 and 2004. The lowest content of DON was found in the cultivars Alka, Malyska and the highest one in the cultivars Vanda and Boka. The positive correlation between the content of DON and FDK (in %) in head (average 2003 and 2004 years) from artificially infected and analysed cultivars was statistically significant in both resistances Type I and Type II.

The Relationship

A total of 126 field studies reporting deoxynivalenol (DON; ppm) content of harvested wheat grain and Fusarium head blight index (IND; field or plot-level disease severity) were analyzed to determine the overall mean regression slope and intercept for the relationship between DON and IND, and the influence of study-specific variables on the slope and intercept. A separate linear regression analysis was performed to determine the slope and intercept for each study followed by a meta-analysis of the regression coefficients from all studies. Between-study variances were significantly (P < 0.05) greater than 0, indicating substantial variation in the relationship between the variables. Regression slopes and intercepts were between -0.27 and 1.48 ppm per unit IND and -10.55 to 32.75 ppm, respectively. The overall mean regression slope and intercept, 0.22 ppm per unit IND and 2.94 ppm, respectively, were significantly different from zero (P < 0.001), and the width of the 95% confidence interval was 0.07 ppm per unit IND for slope and 1.44 ppm for intercept. Both slope and intercept were significantly affected by wheat type (P < 0.05); the overall mean intercept was significantly higher in studies conducted using winter wheat cultivars than in studies conducted using spring wheat cultivars, whereas the overall mean slope was significantly higher in studies conducted using spring wheat cultivars than in winter wheat cultivars. Study location had a significant effect on the intercept (P < 0.05), with studies from U.S. winter wheat-growing region having the highest overall mean intercept followed by studies from Canadian wheat-growing regions and U.S. spring wheat-growing regions. The study-wide magnitude of DON and IND had significant effects on one or both of the regression coefficients, resulting in considerable reduction in between-study variances. This indicates that, at least indirectly, environment affected the relationship between DON and IND.
