Molecular and genetic methods of analysis of genetic polymorphism are highly promising for the evaluation of the diversity of natural populations of rare plant species, including Pancratium maritimum. The works in this direction allow to establish the state of species on the genetic level and to identify the processes of depletion of the gene pool, due to the reduction of the number of species observed in the last decade. The ISSR-markers (inter simple sequence repeat) are widely distributed in the scientific field. The direction of the present study is the selection of effective ISSR markers for genotyping samples Pancratium maritimum cultured in vitro. Pancratium maritimum is a species in a Red book. In the Russia it is only in the Krasnodar Region. Based on the goal of the work the selection of ISSR-markers was carried out to obtain reproducible PCR-fragments. The subsequent determination of the most polymorphic markers from the number selected was conducted further. In the course of the study ISSR-markers UBC818, UBC864, UBC813, UBC825, UBC880, UBC811, UBC827 were tested on 9 samples of Pancratium maritimum. UBC818 and UBC864 markers that showed the clear easily interpretable PCR products were selected. A high level of polymorphism was revealed for marker UBC818 on these samples of Pancratium maritimum. By this marker for used samples of Pancratium maritimum 3 unique fragments were revealed. Selected markers will be further used to estimate the genetic polymorphism of Pancratium maritimum growing on the Black Sea coast of the Caucasus, as well as to analyze the stability of the genotype in a long-term culture in vitro.
