Red Delicious
The Red Delicious is a clone of apple cultigen, now comprising more than 50 cultivars, first recognized in Madison County, Iowa, in 1880. According to the US Apple Association website, it is one of the fifteen most popular apple cultivars in the United States.
Pink Pearl (apple)
In 1940, after many years of work on breeding red-fleshed apples, Etter set up a partnership with George Roeding Jr.'s California Nursery Company, one of the goals of which was to introduce some of Etter's Surprise-derived cultivars to the public. Eventually Roeding settled on test seedling #39, which apparently impressed him with its looks (translucent skin, medium size, and tapered shape), its tart-sweet flavor, and its late-summer ripening date. He secured U.S. plant patent 723 for it on Etter's behalf, named it 'Pink Pearl', and featured it in his 1945 catalog.
