by Sicyos SPP. In the Eastern Black Sea Region, the invaders found in cultural plants, on the roadside and in non-agricultural areas are foreign herbs. The plant is an invasive foreign herb that is easily adapted to the environment in which it is with its climbing and climbing structure and is under pressure by competing with other plants. In this study, thirty Sicyos spp were taken from the different points of the Army and the provinces of Giresun.In determining the genetic characterization of the population samples, ribosomal DNA (rDNA) internal transcribed spacer (ITS) genes are used. The analysis was done using Neighbour-Joining (NJ), Maximum-Parsimony (MP) and Maximum-Likelihood (ML) algorithms. According to the results, two haplotips were found. Haplotip-1 and Haplotip-2 respectively S. davilae Rodr.-Arév. And Lira and S. angulatus L. are 100% similar. Genetic relativity between nine samples and Haplotip-1 was identified at a rate of 68% and 74% (NJ/MP) respectively. There were similarities between the six samples and Haplotip-2 at 69, 80% and 70% (NJ/MP/ML) respectively. by S. Davilae Rodr.-Arév. & Lira is a new species for our country’s flora.
