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 that the category of affine varieties can be identified with a full subcategory of affine schemes over "k". Since morphisms of varieties are obtained by gluing morphisms of affine varieties in the same way morphisms of schemes are obtained by gluing morphisms of affine schemes, it follows that the category of varieties is a full subcategory of the category of schemes over "k". For more details, see . A morphism between varieties is continuous with respect to Zariski topologies on the source and the target. The image of a morphism of varieties need not be open nor closed (for example,
