Chickpea (Cicer arietinum) wilt and root rot are the most relevant diseases in several production areas. There are some lineage of Fusarium oxysporum f. sp. ciceris, from the F. solani and F. redolens complex associated with the wilt symptom. The external disease symptoms are similar; however, both species show different colonization. Traditionally, for many years, the taxonomy of the Fusarium genus has been based on the evaluation of morphological markers, being an irrelevant technique to identify species or phylogenetic lineage. Nucleotide sequencing techniques in species from the genus Fusarium have broke down species into several different phylogenetic lineages, which are currently called the species complex. Thus, it is believed that many pathogens associated with chickpea that are currently denominated as formae speciales may be complex of phylogenetic lineage. Fusarium species of different Fusarium complex have the ability to induce wilt in different hosts, while other species or phylogenetic lineage, have the ability to induce rot root.
