Fuji (apple) the exclusion of other varieties and Japan's apple imports remain low. Aomori Prefecture, home to the Fuji apple, is the best known apple growing region of Japan. Of the roughly 900,000 tons of Japanese apples produced annually, 500,000 tons come from Aomori. Outside Japan, the popularity of Fuji apples continues to grow. In 2016 and 2017, Fuji apples accounted for nearly 70% of China's 43 million tons grown. Since their introduction into the U.S. market in the 1980s, Fuji apples have gained popularity with American consumers — as of 2016, Fuji apples ranked number 3 on the US Apple Association's
Morphism of algebraic varieties Morphism of algebraic varieties In algebraic geometry, a morphism between algebraic varieties is a function between the varieties that is given locally by polynomials. It is also called a regular map. A morphism from an algebraic variety to the affine line is also called a regular function. A regular map whose inverse is also regular is called biregular, and they are isomorphisms in the category of algebraic varieties. Because regular and biregular are very restrictive conditions – there are no non-constant regular functions on projective varieties – the weaker condition of a rational map and birational maps are frequently used
