Other claims from this paper (11)
- Observation Spreader row systems were the most common field screening method in seven studies.
- Observation Conidial spray inoculation was among the most common field screening methods in six studies.
- Method / resource The glasshouse sandwich technique generated the highest disease pressure.
- Method / resource Resistance screening methods showed strong cross-method correlations of r = 0.92–0.99.
- Observation QTL mapping found resistance loci on chromosome 2.
- Observation QTL mapping found resistance loci on chromosome 3.
- Observation Chromosome 6 carried resistance loci stable across multiple pathogen species.
- Observation Certainty of evidence for method effectiveness was moderate.
- Observation Certainty of evidence for molecular markers was low.
- Method / resource Established phenotypic screening methods reliably discriminate resistant germplasm.
- Recommendation The authors call for standardised protocols, broader geographic validation, and independent molecular marker confirmation.
