No cultivar name of record
This patent does not name the plant. Through the 1980s and early 1990s that was still common: naming every new cultivar only became standard practice as plants began to be marketed under brand names. The grant identifies this one by its number and by a written description instead.
Nothing here is missing from our records: the patent itself states no name. Where one exists we show it, and we do not invent one.
Abstract
A new and distinct variety of grapefruit hybrid citrus tree characterized by a maturity habit a full six months earlier than grapefruit grown in the same areas and further characterized by its nearly seedless white-fleshed fruit which is sometimes slightly bitter and has a flavor similar to 'Oroblanco' but more like pummelo. Fruit is tender and juicy and flesh separates will from segment membranes.
