Moro Blood Orange

The Hodgson cultivar description reproduced by UCR attributes Moro to comparatively recent Sicilian origin and says it is thought to have developed from Sanguinello Moscato; UCR lists the CRC 3811 accession’s parents as unknown. Fruit is medium to medium-large, subglobose, round or obovoid, with a somewhat furrowed base, commonly flattened apex and faint or absent areole; seeds are few or absent, sometimes with a purplish-red chalazal spot. The medium-thick, moderately adherent, somewhat pebbled rind is orange at maturity, sometimes with a light-pink blush or red streaks later. Flesh is deeply pigmented, juicy and described as pleasant in flavor. Moro is among the earliest commercial blood oranges; fruit holds on the tree and stores and ships well. A distinctive aroma develops with advanced maturity, but flavor can deteriorate if fruit is stored too long and become objectionable to some.^⁠[1]

UCR describes a medium-vigor, spreading, round-topped tree with productive fruit clusters. In one 2 Minute Garden Tips account, a small container Moro in its third full season produced a reported 11 lb harvest at once, with about a dozen more fruit picked earlier in winter; this is a single-tree report, not a typical yield estimate.^⁠[1]⁠[9]

UCR’s reproduced cultivar account describes early, strong flesh pigmentation and often weaker rind coloration. It reports little external pigmentation in coastal southern California, while internal color remained pronounced.^⁠[1]

Growers describe differing color and flavor impressions from individual Moro fruit. A store-bought comparison describes dark red exterior color and mostly berry flavor, while other growers report raspberry notes, mild sweetness, or a sweet fruit with an acidic bite. These subjective reports vary by sample; UF/IFAS also notes blood-orange pigmentation varies with cultivar, climate, cultural practices, rootstock, maturity and harvest timing.^{⁠[6]⁠[7]⁠[8]⁠[11]⁠[4]⁠[3]}
