Plant Genetic Resources are factor that contribute limiting of ecological erosion and they are a source of useful characteristics for adaptation of crops to the growing negative impact of the climate changes. Forage crops occupy a solid part of the conserved genefund. Their origin and species composition diverse determine the need of trait evaluation of accessions, which is essential for their effective utilization in plant breeding programs. The aim of the study is to analyze the genetic diversity in collection of local Lathyrus sp. and Dactylis sp. accessions on the basis of an agro biological study. The cluster analysis combines forage crops in four groups, showing genotypes with distinct high values of number of branches to the main stem, number of pods and seeds per plant and mass of 100 seeds. The forage grass accessions are divided into five cluster groups and genotypes suitable as donors of economically significant qualities responsible for productivity are found.
