초록

The persimmon cultivar Gamnuri (Diospyros kaki Thunb.) is a new pollination-constant astringent (PCA) type developed by the Sweet Persimmon Research Institute of Gyeongsangnam-do Agricultural Research & Extension Services. This cultivar was selected from the seedlings of the cross between the Sunami and Johongsi cultivars in 1997. After being selected as a prominent seedling line in 2006, its tree growth and fruit characteristics were investigated from 2016 to 2017. The tree grew vigorously during the young stage and showed a spreading shape as it aged. Only female flowers bloomed. The flowering and harvest dates were May 20 and October 16, respectively, which was similar to that of the Sangju-Dungsi control cultivar. The fruits of Gamnuri were characterized by a red-orange skin color with a round, flat shape. The average fruit size was 370 g, which was 1.7 times larger than that of the control. Ninety-three percent of the fruit was marketable with a rare occurrence of calyx-end cracking, which was similar to that of the Sangju-Dungsi cultivar. The soluble solids and flesh firmness were 16.7°Bx and 15.8N, respectively, which was lower than that of the control. Notably, matured fruits maintained their quality for an extended period of time on the tree. When the fruits from the Gamnuri cultivar were processed into sliced-dried fruits, the product had a great taste with good color.
