Abstract

Septoria tritici blotch reactions in seedling plants in thirty-four winter wheat genotypes originated from the Great Plains of the USA were evaluated. Among them, eight were resistant to septoria tritici blotch, two were moderately resistant, and nine moderately susceptible. The repeatability of septoria tritici blotch assays obtained by partitioning of variance components was very high (94.0 ± 2.0%). Our results suggest that seedling septoria tritici blotch screening provides consistent information on host response, and repeated evaluation may not be necessary to obtain reliable host reaction information.
