Pyrus communis genotypes were obtained from Ardahan province, Turkiye. A total of 15 RAPD and 18 ISSR primers were used to determine the molecular genetic diversity of the Pyrus communis genotypes. For trnL intron, trnC, trnD, for trnL-F, trnE, and trnF primers were used in PCR for amplification. In all, 57 and 91 bands were obtained by RAPD and ISSR analysis, respectively. Polymorphism rates were 78.94% and 85.71%, respectively. For trnL intron analyses, the average nucleotide composition consisted of 39% thymine, 17.5% cytosine, 28.4% adenine, and 15.1% guanine. In trnL-F assays, the average nucleotide composition consisted of 31.9% thymine, 14.4% cytosine, 37.5% adenine, and 16.1% guanine. The results of the phylogenetic tree constructed with trnL intron and trnL-F sequences of Alchemilla, Rosa, Sorbus, Malus, Prunus, and Cotoneaster species of the Rosaceae family obtained from NCBI were found to be similar. As a result of the study, polymorphisms were obtained at the rates of 78.94% and 85.71% from RAPD and ISSR analyses, respectively. In conclusion, detailed phylogenetic relationships of pear genotypes using chloroplast trnL intron and trnL-F sequences with respect to other species from the same family were revealed.eninfo:eu-repo/semantics/closedAccessMolecular MarkerPearTrnl IntronTrnl-FTurkiyeArticle10.1007/s10341-022-00798-06522312402-s2.0-85145210773Q2WOS:000905846500004Q3
