Timeline of United States discoveries
The Red Delicious is a clone of apple cultigen, now comprising more than 50 cultivars. The Red Delicious apple was discovered in 1875 by Jesse Hiatt on his farm in Peru, Iowa. Believing that the seedling was nothing more than nuisance. After chopping down the tree three times, Hiatt decided to let the tree grow and eventually, it produced an unknown and new harvest of red apples. Hiatt would eventually sell the rights to this type of apple to the Stark Brothers Nurseries and Orchards who renamed it the Red Delicious.
Fuji (apple)
The Fuji apple is an apple hybrid developed by growers at Tohoku Research Station (農林省園芸試験場東北支場) in Fujisaki, Aomori, Japan, in the late 1930s, and brought to market in 1962. It originated as a cross between two American apple varieties — the Red Delicious and old Virginia Ralls Genet (sometimes cited as "Rawls Jennet") apples. According to the US Apple Association website it is one of the fifteen most popular apple cultivars in the United States. Its name is derived from the first part of the town where it was developed: Fujisaki.
