A new early maturing satsuma mandarin (Citrus unshiu Marc.) ‘'Haryejosaeng’' was developed as a nucellar seedling selection of ‘'Tachima Wase’' (C. unshiu Marc.) that was crossed with C. natsudaidai Hayata at the National Institute of Subtropical Agriculture in Jeju island in 1992. The ‘'Jegam ga No. 2’', a first selection from the seedlings fruited in 2001 was finally named “"Haryejosaeng”" through field evaluation trials at three locations in Jeju island from 2003 to 2004. ‘'Haryejosaeng’' produces seedless fruit maturing in early November, and has higher soluble solids and lower acidity than ‘'Miyagawa Wase’', the leading early-maturing satsuma mandarin cultivar in Jeju island. Fruit weight is moderate at about 80～90 g and its shape is compressed-oblate globose with a light orange color. The rind thickness of about 2 mm provides easy peeling. The flesh shows light orange colored and contains 10 to 11 Brix and 1 to 1.1% acidity when mature. Tree shows vigorous growth and spreading thornless twigs. Alternate bearing is similar to ‘iyagawa Wase’ ‘aryejosaeng’is susceptible to citrus scab disease and melanose, but resistant to citrus canker.
