*4.3. Candidate Gene Prediction*

Here, we identified five genes that are related to disease resistance in the *CQPc5.1* QTL region. We identified three genes annotated as disease-resistance protein RPP13-like; *RPP13* was a singleton NBS-LRR gene located in *CQPc5.1* on Chr05. *Capana05g000595* gene was identified as disease resistance protein RPP-8. Two genes (*Capana05g000596* and *Capana05g000597*) were annotated to be disease resistance protein RPP13-like. *RPP13* is a CC (coiled-coil)-NBS-LRR domain-containing *R* gene that controls resistance to *Peronospora parasitica* oomycete pathogen in *Arabidopsis thaliana* [53,54]. These two candidate genes encode *RPP13*-like NBS-LRR proteins and serve as potential candidates for *P. capsici* resistance in pepper. *Capana05g000598* was annotated as a probable LRR receptor-like serine/threonine-protein kinase. *Capana05g000604* was annotated to be an F-box/LRRrepeat protein. Several LRR domain proteins have been determined to participate in defense responses to infiltrating pathogens [12,55–57].
