Brazilian citriculture is been blessed with great news: an orange variety that is naturally resistant to the bacterium that causes yellowing. The disease, also called citrus variegated chlorosis (CVC), has haunted Brazilian orchards since the 1980s, and can be spread by insects or contaminated seedlings. The Navelina XR orange was presented on Tuesday during the 48th Expocitros and 44th Citriculture Week. It is being released alongside a sweet orange variety and a lime variety, both of which are precocious. The three are the result of research in partnership between Embrapa , the Coopercitrus Credicitrus Foundation (FCC) and the Sylvio Moreira Citriculture Center (CCSM), linked to the Agronomic Institute (IAC).
The Navelina XR is the only orange tree naturally resistant to the bacterium that causes citrus variegated chlorosis (CVC), without suffering damage or being a host or source of relevant inoculum.
