Leaf mold of Solanum lycopersicum x Solanum pimpinellifolium interspecific hybrid
Solanum lycopersicum x Solanum pimpinellifolium
The causal agent of leaf mold in Solanum lycopersicum x Solanum pimpinellifolium hybrids is the fungus Passalora fulva. Resistance to the pathogen is controlled by specific Cf genes, which are sourced from wild species.
In the reference 3 varieties crop Tomato, where this is mentioned in the description.
Genetic control of resistance in interspecific tomato hybrids to Passalora fulva is mediated by Cf loci inherited from the wild species Solanum pimpinellifolium. The breeding process utilizes both classical genes from Cf-1 to Cf-9 and modern markers to identify the allelic status of genes such as Cf-12 and Cf-19.
Despite the active use of this hybrid in breeding, no specific forms of pathogenesis or unique pathogen races characteristic exclusively of this plant group have been identified. The resistance of cultivars and hybrids of this origin is confirmed by molecular genetic testing for the presence of the corresponding Cf genes.
