Abstract: | Summary On average, the cereal species studied were susceptible to septoria nodorum blotch (SNB), except for spring triticale on leaf and head and winter titicale on leaf, that appeared to be significantly more resistant, than the other ones.In all three species the SNB response of the adult plants was to a limited extent only predicted by the reaction on first leaf seedlings. In most cases it was impossible to predict the response to SNB of adult plants on the basis of seedling reaction. Correlations between the adult plant stage and the seedling stage, or detached seedling leaves, appears not to be sufficient for use in practical breeding work. A reversal of reaction to SNB was even found between the above growth stages in studied spring and winter wheat varieties. |
