Abstract Concerns about food security worldwide have been raised due to the adverse impacts of climate change on agricultural productivity. Utilizing wild relatives of cultivated plants in breeding schemes is a potential solution to address the abovementioned challenges. Wild relatives refer to indigenous plant species that share genetic ancestry with recently cultivated plants. The capacity of plants to withstand abiotic stresses and enhance crop yield stability in cold and arid environments renders them a valuable prospective resource for breeding programs. phytochemicals and genetic markers are employed to assess the genetic variability of cultivated plants and their wild relatives under investigation from eight families: Apiaceae, Asteraceae, Brassicaceae, Convolvulaceae, Lamiaceae, Fabacae, Poaceae and Solanaceae and also identification of species by using DNA barcoding (ITS region) that create a communal database of DNA sequences that can be clarified their taxonomic classification. Overall, the results obtained suggest a significant degree of genetic diversity and relatedness among the cultivated taxa and their wild relatives examined in this study |
