Hovenia dulcis var. koreana Nakai is recently known to be a useful tree because of their medicinal function. In 1996, candidate trees were selected from 10 regions in Korea, and a clone bank was established in 1998 by grafted 70 candidate clones of candidate trees in order to breed high-yield superior trees. From 2003 to 2005, five clones were selected and screened by analyzing flowering and fruiting characteristics of 47 clones in the clone bank. “Poong-Sung 1”, a new high-yield superior H. dulcis var. koreana Nakai cultivar was finally selected from the 5 clones. The final selection focused on fruiting characteristics such as the number of fructify lateral (NFL), the number of average bunch per one fructify lateral (NABFL), the number of average bunch per fruiting lateral (NABPFL), the weight of fruit petiole per individual (WFPI) and the yield of individual (YI). Fruit petiole of “Poong-Sung 1” has dark brown skin color and fruit flesh color. Fruiting characteristics of “Poong-Sung 1” showed large better results and selection effects with an average of 19.3Ea (NFL), 4.75Ea (NABFL), 91.68Ea (NABPFL), 4.7 kg (WFPI) and 11.26 kg (YI) which are 158.8%, 147.1%, 233.9%, 401.7% and 412.5% superior compared to the mean of 47 clones, respectively.
