Abstract

This study presents a systematic analysis of the Rosa L. genus and selected species based on morphological characteristics and DNA markers. Species such as Rosa kokanica, Rosa canina, Rosa ecae, Rosa fedtschenkoana.were examined in detail through the assessment of diagnostic morphological traits, including leaf shape, flower structure, fruit morphology, and prickles. In addition to morphological evaluation, molecular phylogenetic analysis was conducted using DNA markers, particularly the Internal Transcribed Spacer (ITS) region and chloroplast DNA (cpDNA) sequences. The results revealed genetic relationships and phylogenetic affiliations among the studied species, contributing to a clearer understanding of their systematic placement within the genus. The integration of morphological and molecular data provided deeper insights into the taxonomy of Rosa species, clarifying certain ambiguities in traditional classifications. These findings are valuable for the advancement of modern botanical systematics, conservation strategies, and the effective management of genetic resources within the Rosa genus.
