Summary
Progenies of a cross between pepper cultivar Delray Bell (Capsicum annuum L.) tolerant to pepper mottle virus (PeMoV) and P.I. 159236 (Capsicum chinense Jacq.), resistant to PeMoV were evaluated in greenhouse experiments. The F1 generation was susceptible to PeMoV, whereas the backeross generations to both parents and the F2 segregated in a ratio of 1:1. This indicates that PeMoV resistance is controlled at the same locus in both parents or at two closely linked loci. Each parent is homozygous for one locus and the homozygous condition of either allele results in failure to support virus; in heterozygous condition as observed in the F1 generation, the effect of a single allele is insufficient even when one allele of each type is present, resulting in systemic infection.
