Citrange CARRIZO

(Citrus sinensis Osbeck x Poncirus trifoliata Raf.). Obtained in Florida in 1909, it spread throughout the world because, when combined with sweet orange, it resists the tristeza virus (CTV). It is tolerant to Psoriasis (CPsV) and Xyloporosis (CCaVd) but is susceptible to Exocortis (CEVd). It has a deep and widespread root system and is considered similar to all commercial varieties, but is mainly used in combination with sweet orange varieties. It exhibits disaffinity phenomena only when combined with Eureka lemon and Mapo tangelo. It has some problems in calcareous soils (over 7-8%), is sensitive to excess and lack of humidity, and is moderately tolerant to salinity. It imparts a certain tolerance to cold to the scion. It tolerates attacks by Phytophthora spp., while it is sensitive to attacks by Fusarium spp. It tolerates nematodes but is sensitive to Radopholus similis. It provides good productivity in terms of both quantity and quality, abundant yields, and large, high-quality fruit. In pigmented cultivars, it induces intense anthocyanin coloration.
