Notes and observations

WPB: A variegated orange containing alternating striped of light and green color before maturity. Leaves ornamental. Said to be a commercial variety in Brazil. Note: This should not be confused with the acidless Imperiale from Spain.

3/23/1987, EMN: Fruit is variegated, having corrugated rind with varying color stripes; flavor is fair. Might have ornamental potential.

1/13/1988, EMN:Fruit has pretty good flavor but is moderately seedy. Will plan to enter this accession as a new VI and move to the Lindcove foundation block.

11/1989: Was entered as VI 473 in fall 1988 but had psorosis; put into Thermo, which plants did not push well. Sched. to re-enter in 1990.
