Product Name: Harumi Mandarin (ChunJian / Papa Gan)
Description:
Harumi Mandarin, widely known in China as ChunJian (春见) or affectionately as Papa Gan (Papa Gan), is a premium late-season mandarin variety developed in Japan in 1979 by crossing 'Kiyomi' tangor with 'Ponkan F-2432'. It was introduced to China in 1999 and has since become one of the most beloved citrus varieties in the Sichuan region, earning the title "King of Hybrid Citrus" .
A Citrus That Lives Up to Its Name:
The name “ChunJian” means "meeting in spring" , a poetic reference to its harvest season around the Spring Festival . But it is the Sichuan nickname “Papa Gan” that truly captures its character – “Papa” means “soft” in the Sichuan dialect, describing the way the fruit’s skin and flesh separate, giving it a delightfully soft, yielding feel in the hand .
Flavor & Texture:
Harumi Mandarin delivers an exceptional eating experience. The flesh is crisp, tender, and bursting with juice, with an almost complete absence of acidity – soluble solids reach 14° Brix or higher, while acidity is only around 1% . The segments are thin-walled and melt in your mouth (化渣) , and the fruit is seedless, making it exceptionally convenient to enjoy . Among its close relatives – Papa Gan, Shiranui (ugly orange), and Kiyomi – Papa Gan is widely regarded as having the most universally appealing flavor .
Appearance:
The fruit is high-flat round to oblate, with a smooth, glossy orange-yellow skin that is easy to peel. It is more rounded and uniform than its "cousin" Shiranui, with a smaller or absent neck . Average fruit weight is 220–300 grams, with an edible rate of approximately 78.64% .
