Reaction of wild solanaceae species to Meloidogyne incognita1

ABSTRACT The quest for resistance sources against Meloidogyne incognita as a control measure is essential in tomato. [...]this study aimed to evaluate the reaction of six species of wild solanaceae to M. incognita. The Mi gene confers resistance to M. incognita, M. javanica, M. arenaria (Neal) Chitwood (Cook, 1991), but there are few resistant commercial cultivars and the Mi gene does not confer resistance to new species such as M. brasiliensis Charchar & Eisenback and M. enterolobii Yang & Eisenback (formerly M. mayaguensis Rammah & Hirschmann) (Charchar et al. 2010; Pinheiro et al., 2014b). [...]the identification of new resistance sources similar to Mi gene in the Solanaceae family are fundamental for the management of Meloidogyne in tomato. Species of wild solanaceae have been reported as resistant against M. javanica, M. incognita race 1 andM. enterolobii (Mattos et al, 2011; Cardoso et al, 2019). [...]the search for new wild resistant solanaceae againstM. incognita contributes as a strategy to develop resistant rootstocks and genetic sources of resistance for tomato. [...]the objective of this work was to evaluate the reaction of six species of wild solanaceae to M. incognita.
