Selection of varieties resistant to diseases of soil-borne plant pathogens is the most efficient, economical and sustainable method. In this study, the resistance of Phytophthora crown blight (<em>Phytophthora capsici</em> Leon.) disease on 95 pepper genotype in terms of yield and some quality characteristics was investigated by using SCAR marker (OpD04.717). In the study, pepper lines in 7 pepper genotype F2 population showed durability band at 717 bp of agarose gel, while 88 pepper genotype were found to be sensitive. As a result of molecular studies, 7 pepper genotype resistant to <em>Phytophthora capsici</em> Leon. were also confirmed by classical test using seedling immersion method. In the study, as a result of molecular and classical tests, <em>Phytophthora capsici</em> Leon. is determined to be resistant to pepper lines in the hybridization programs to obtain new varieties and will be used as a parent or father will contribute to improvement studies.</p> ER -
