The ‘Jangwon’ 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 and easy peeling in 2010. This cultivar was first selected from a natural population in 2001, and the preliminary trials for evaluation were carried out from 2007 to 2009. The harvest time of ‘Jangwon’ was the second week of September and the total yield of an 8-year-old tree was 3.9 kg. Also, ‘Jangwon’ was a suitable cultivar for making roasted peeled products because its soluble solid content was 17.5%, kernel hardness was 9.6 kg·cm2, and pellicle removability was 98.6%, which were much higher than those of the control cultivar, Arima. Furthermore, this cultivar is suitable as a pollinator for the improvement of pellicle removability of other chestnut trees.
