Other claims from this paper (12)
- Observation Broomrape race F overcame known resistance genes in cultivated sunflower.
- Observation All hybrids currently grown in Spain were susceptible to race F.
- Observation Most perennial wild Helianthus species were completely resistant to race F.
- Observation Some H. divaricatus accessions had 10 to 80% incidence of susceptible plants.
- Observation Some H. maximiliani accessions had 10 to 80% incidence of susceptible plants.
- Observation Some H. pauciflorus subsp. pauciflorus accessions had 10 to 80% incidence of susceptible plants.
- Observation H. anomalus was fully resistant.
- Observation H. agrestis was fully resistant.
- Observation H. debilis subsp. cucumerifolius segregated for resistance.
- Observation H. exilis segregated for resistance.
- Observation 7.2% of cultivated sunflower accessions were fully resistant.
- Recommendation The authors concluded that resistant sunflower cultivars could be developed from the observed germplasm.
