Origin & Breeding History: 'Mihaya' originated from a controlled cross-pollination conducted in 1998, at the Institute of Fruit Tree Science - Kuchinotsu Citrus Research Station, Minami-shimabara, Nagasaki, Japan, between the variety 'Tsunonozomi', as the female parent, and a proprietary variety as a male parent. From the resulting progeny, 'Mihaya' was selected in 2002 for fruit characteristics such as visual appearance, ease of peeling, and good taste.
Tests & Trials: The detailed description of 'Mihaya' is based on the UPOV report of Technical Examination, application number 26541, purchased from the Plant Variety Protection Office, Intellectual Property Division, Food Industry Affairs Bureau, Minister of Agriculture, Forestry and Fisheries, Japan. The documents related to test and trials were examined by the Plant Variety Protection Office in Japan and granted rights on September 30, 2014.
