Molecular Characterization, Population Structure Analysis, and Association Mapping of Turkish Parsley Genotypes Using iPBS Markers

Abstract

Parsley (Petroselinum crispum Mill.) is a vegetable that has many benefits for human health, and its cultivation is increasing. In order to carry out breeding studies in parsley, genotypes should be characterized in terms of some characteristics. In this study, some phytochemical properties of 18 different parsley genotypes were revealed, and their genetic diversity was determined with the iPBS (Inter Primary Binding Site) marker system. In the study, the polymorphism rate was 31.9%, the mean PIC (Polymorphic Information Content) was 0.17, and the similarity coefficients were between 0.87 and 0.99. The number of subpopulations was determined as two, and 10 markers were detected at expression levels of 19–33% related to phytochemical properties. The results of this study show that there is a phytochemical and genetic variation in parsley. Parsley genotypes with certain phytochemical properties and genetic structures can be used more effectively in breeding programs.
