Provided the original grafted seedling to John Panzarella for evaluation around July 1989.
The Panzarella Citrus article’s first-person narrator says Chapman gave them the grafted seedling around July 1989 and asked them to grow it to see what fruit it would produce. The narrator says it fruited several years later. The article displays no byline and does not name the recipient in this passage.
Made the Umatilla tangor × Moro blood orange hybridization from which Raspberry Tangor originated.
Panzarella Citrus reports that Bill Chapman of League City, Texas, pollinated a monoembryonic Umatilla Tangor flower with Moro Blood Orange pollen. Chapman grew fruit from the cross, collected its seed, and grafted a seedling bud. The article does not state when or where the pollination took place; it says the resulting grafted seedling was later transferred around July 1989.
