Uni- and multivariate approaches to evaluating the susceptibility of wheat hybrids to Fusarium head blight
Fusarium head blight (FHB) is a disease of small grain cereals caused by Fusarium species. The pathogens affect spikes and kernels, resulting in reductions of yield and its quality. The present study was conducted to evaluate variation in the FHB resistance of wheat F2 hybrids derived from 16 crosse...

| description | Fusarium head blight (FHB) is a disease of small grain cereals caused by Fusarium species. The pathogens affect spikes and kernels, resulting in reductions of yield and its quality. The present study was conducted to evaluate variation in the FHB resistance of wheat F2 hybrids derived from 16 crosses between winter wheat cultivars of various origin and with different susceptibility to FHB. Plants were inoculated with a conidial suspension consisting of a mixture of F. culmorum, F. graminearum and F. avenaceum isolates. After harvest 1000-kernel weight, number of kernels per spike and kernel weight per spike were evaluated in inoculated and control plants. Disease symptoms were observed on kernels of infected plants and the percentage of Fusarium-damaged kernels (FDK) was calculated. The data were statistically evaluated using uni- and multivariate analyses. A significant influence of genotype and treatment on all observed characteristics was detected. Contrasts between control and inoculated plants showed that inoculation lowered the mean values of all the yield-related traits significantly (in the statistical sense). Results of uni- and multivariate analyses enabled us to find three cross combinations which exhibited a low FDK percentage and simultaneously a relatively low reduction of 1000-kernel weight after inoculation. They may be promising for breeding wheat with improved resistance to FHB. |
