A new chestnut cultivar, Mipung (Castanea kusakuri Blume), was released from Korean native chestnut trees by the chestnut laboratory of the Korea Forest Research Institute (KFRI) in 2005. This cultivar was first selected from a natural population in 1984, and the preliminary, advanced, and regional yield trials for evaluation were carried out from 1985 to 2005. ‘Mipung’ is a late-ripening cultivar with an optimal ripening date in late September. It has good nut quality for eating raw and processing. Average nut weight is 27.3 g, which is much heavier than that of the control cultivar, Arima (C. crenata). It is also identified as resistant to chestnut blight disease and chestnut gall wasp. The average yield of 8-year-old ‘Mipung’ was 8.8 kg per tree, which is superior to that of ‘Arima’.
