Fuji (apple) received US plant patents by August, 2008: Unpatented Fuji mutants include: 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
History of manifolds and varieties History of manifolds and varieties The study of manifolds combines many important areas of mathematics: it generalizes concepts such as curves and surfaces as well as ideas from linear algebra and topology. Certain special classes of manifolds also have additional algebraic structure; they may behave like groups, for instance. In that case, they are called Lie Groups. Alternatively, they may be described by polynomial equations, in which case they are called algebraic varieties, and if they additionally carry a group structure, they are called algebraic groups. The term "manifold" comes from German "Mannigfaltigkeit," by Riemann. In English, "manifold" refers to
