Increasing attention has also been given to dissecting and understanding diversity in relation to genes underlying important agronomic traits in a number of crops. Molecular phylogenetics and genetic diversity analysis can help to clarify the taxonomic identity and evolutionary relationships of the wild relatives of crop species. These methods can also help prevent misidentification and carefully plan effective germplasm management strategies. Variability and genetic diversity are important factors in evolution and also in applied sciences because they determine the responses of a given organism to, for example, to environmental stress, natural selection and susceptibility to different diseases
