Abstract

Genetic diversity analysis is an important tool in crop improvement. Species with high genetic diversity are a valuable source of variation used in breeding programs. The aim of this study was to assess the genetic diversity of four species belonging to the genus Aegilops, which are often used to expand the genetic variability of wheat and triticale. Forty-fve genotypes belonging to the genus Aegilops were investigated. Within- and among-species genetic diversity was calculated based on REMAP (retrotransposon–microsatellite amplifed polymorphism) molecular markers. Obtained results showed that REMAP markers are a powerful method for genetic diversity analysis, which produces a high number of polymorphic bands (96.09% of total bands were polymorphic). Among tested genotypes, Ae. crassa and Ae. vavilovii showed the highest genetic diversity and should be chosen as a valuable source of genetic variation.
