Narrative

Moro is described in [Hodgson, 1967] on pp 473 and is picturedi in coloor on pp 467[; also see Saunt, 2000, p 37].

This accession appears identical to [PI 539550] - Moro. Nearly seedless, flavor fair, not as good as Ruby or Tarocco. Best external color is on fruits on north side of trees. See blood orange color comparison chart [on record for PI 238796]. (EM Nauer, 2/4/1988)

There were formerly two selections of 'Moro' maintained at Riverside: this one and PI 539550. Both were apparently selections from seedling sources. PI 539554 was originally selected at the USDA Date and Citrus Station in Indio, California. At some point, it was established in the Nucellar Block at the UC Lindcove Research and Extension Center. Whether or not it was received as seed or as budwood is not clear, but the LREC trees were the source of the VI. Since this is the VI budline and there appears to be no difference between this and PI 539550, the latter was inactivated. Additional Information and pictures are availanble from the UC Riverside Citrus Variety Collection and the Citrus Clonal Protection Program. (RR Krueger, 7/3/2015)
