Özet
Abstract
Althougt Turkey has big potential with regard to production area and quality pepper production, equated yield is low
because of plant diseases. One of the plant diseases is Phytophthora capsici Leon. Tolerance of this disease in pepper
species is controlled by more than one gene (QTL). Until now, there are some reports on QTL mapping for disease
tolerance in pepper species and one of them is Phyto.5.2 which is linked to Phytophthora capsici Leon. disease
tolerance. In this study, we aimed transfer disease tolerance to pepper genotypes which are grown in Central Anatolia
region. Crossing was carried out between Cırgalan pepper and P1(tolerant to Phytophthora capsici Leon) and
backcrossed to Cırgalan pepper genotype to obtain BC1F1. BC1F1 plants were tested using molecular marker which
linked with Phyto.5.2 QTL. Tolerant plants were backcrossed with Cırgalan pepper genotypes to obtain BC2F1 plants.
BC2F1 plants were tested again using molecular markers and tolerant plants selfed to obtain BC2F2. After testing,
anthers of tolerant plants were inoculated to get double haploid plants. From the results obtained, 25 pure industrial
pepper lines were obtained which had Phytophthora capsici Leon. disease tolerance. These lines will be useful for
Phytophthora capsici Leon. disease tolerance breeding programs.
