Title
Variation in Septoria musiva and Implications for Disease Resistance Screening
Kathleen Ward; Michael E. Ostry Plant Disease 2005
Other claims from this paper (6)
- Observation Septoria musiva isolates differed in aggressiveness in hybrid poplar leaf disk and stem assays.
- Observation The isolates differed in culture growth in vitro.
- Observation Clone by isolate interactions occurred in one stem assay but not leaf disk assays.
- Observation The isolates showed large genetic similarity but each had a unique RAPD pattern.
- Recommendation The authors suggest that selecting the most aggressive isolate may be unnecessary for resistance screening.
- Recommendation The authors suggest choosing isolates that best discriminate resistance variation among screened clones.
