The ‘Jahong’ chestnut (Castanea crenata Siebold & Zucc) was released from Korean native chestnut trees by the Korea Forest Research Institute (KFRI) to develop cultivars with desirable nut characteristics such as high sweetness, easy peeling, and a hard kernel in 2009. This cultivar was first selected from a natural population in 2001, and the preliminary and advanced trials for evaluation were carried out from 2003 to 2007. ‘Jahong’ is a medium-ripening cultivar with reddish burrs distinct from any other cultivars between late July and mid-August before ripening. With its distinct red color, this cultivar could provide beauty in ornamental tree cultivation. ‘Jahong’ is a suitable cultivar for eating raw and making roasted peeled products, because its soluble solid content is 16.3%, kernel hardness is 10.3 kg·cm–2, and pellicle removability is 90.0%, which are much higher than those of the control cultivar, Arima (Castanea crenata Siebold & Zucc). This new cultivar is also suitable as a pollinator for the improvement of nut quality such as sweetness and pellicle removability.
