Other claims from this paper (5)
- Observation The four rust races distinguishable with two resistance factors were found in Manitoba.
- Observation Most rust collections outside Manitoba were classified as race 1 on Canadian differentials.
- Method / resource Rust races identified different resistance factors in sister sunflower selections with identical field reactions.
- Observation Rust-resistant sunflower accessions 953-88 and 953-102 each had at least two distinct resistance factors.
- Observation H. argophyllus has rust resistance factors that appear to differ from those of Canadian differential varieties.
