MEISSNER FILHO, PAULO E. et al. Reaction of hybrid rootstocks to Citrus tristeza virus. Fitopatol. bras. [online]. 2002, vol.27, n.3, pp.312-315. ISSN 0100-4158.

Tristeza caused by Citrus tristeza virus (CTV) is one of the main virus diseases of citrus (Citrus spp.) in Brazil. Some authors have used the intensity of stem pitting symptoms to select resistant plants to tristeza. This work evalueated the reaction of hybrid rootstocks from the citrus breeding program of Embrapa Cassava and Tropical Fruits. Two scales, for hybrid rootstock evaluation of resistance to CTV were elaborated, one photographic and the other diagrammatic. The majority of the analyzed rootstocks showed a low number of stem pitting and was considered resistant to the virus. Resistance was maintained in hybrids when the parent plants presented resistance to CTV.

Keywords : CTV; escala de notas; "stem pitting"; caneluras.
