metadata.artigo.dc.description.abstract: Pvr4 locus, commonly associated with a co‐dominant CAPS marker, confers monogenic dominant resistance to potyvirus complex in Capsicum spp. Aiming to investigate whether the resistance found in resistant genotypes not bearing Pvr4 marker is due to allelism in the Pvr4 locus, or due to a new locus of the pvr series, segregation analyses of an F2 population obtained from a cross between two pepper lines “Myr‐29‐10” (P1) (resistant to PepYMV, showing a single band of 444 bp, Pvr4/Pvr4) and “PIM‐025” (P2) (resistant to PepYMV, showing a single band of 458 bp, Pvr4+/Pvr4+) were performed. According to the results, there is strong evidence that the locus controlling PepYMV resistance in PIM‐025 (P2) is not Pvr4. These results provide evidence that those resistant genotypes, bearing a susceptible band pattern in the Pvr4 locus (458 bp, Pvr4+/Pvr4+), carry a different gene from those described in the literature up to the present time.
