Iseki Citrus unshiu Marc. Mandarina unshiu
'Iseki' has Japanese origin and belongs to the Unshiu tangerine group Wase. It has somewhat smaller fruit that weighs 70g and usually ripens from the end of October until early November. It's an excellent variety which is however often replaced by Miyagawa in Citrus cultivation areas. This is mainly because Miyagawa has significantly higher yields.
