Notes and observations:
A Diller orange is described in TCI, Vol. I, pp 458,where it is spelled Diller. When this accession arrived at the Citrus Variety Collection it was originally spelled 'Dillar', but it seems clear that it is the same accession as 'Diller'.
2/8/1988, EMN: Only 3 fruits but appears to be a typical mid-season, seedy sweet orange.
1/20/1989, EMN: A common mid-season sweet orange. Appears to be about average in all respects; may be slightly less seedy than most sweets.

Fruit small to medium, oblong to slightly ellipsoid; seeds comparatively few. Color bright orange. Rind medium-thick and moderately pebbled. Flesh well-colored, juicy; flavor good. Early in maturity.
