1 WP4 Field experiments with artificial Fusarium inoculation

2 P3: Mattias Hermann, Germany P9: Domnica Daniela, Romania P14: Lenka Nedomova, Czech Republik P8: Luigi Cativelli, Valeria Terzi, Italy (without artificial inoculation) Partner

3 Comparison of planning and course 2008 1.Experimental design: According to Web- application and plan 2.Seeding: As planned, minor differences 3.Inoculation: Nearly as planned, with some problems 4.Trait measurements: Differences due to local circumstances/conditions

4 First Results Precision of the experiments? 1.Comparison variances over locations and estimation of Cultivar x Location interaction effects 2.Coefficients of correlations between locations

5 ANOVA for replicated standard cultivars ( PLABSTAT )

6 ANOVA continuation

7 Coefficients of correlation (I)

8 Coefficients of correlation (II)

9 Conclusions: Interactions and variances normal as expected; Good concordance between single experiments in high heritable traits

10 Inoculation results 1.Romania: Successful, but assessment of field symptoms very difficult, only yes or no; FDK-seed percentages are better in differentiation 2.Czech Republik, Italy and Germany: Nearly no visual symptoms in plots or harvested kernels (but in Aranka) 3.ELISA results are needed for further differentiation

11 Coefficient of correlation between FHB- scorings and other traits (Romania)

12 Comparison between inoculated and noninoculated plots (effects of inoculation)

13 Summary and conclusions Experimental design and realisation good Viewable Fusarium infection low, possible reasons are resistances, weather conditions, low virulence of Fusarium isolates used, etc. No correlation of Fusarium infection level and other traits, as in other studies ELISA results are needed for further differentiation
