‘Olnuri’ is a new variety of early ripening sweet persimmon obtained in 2006 by crossing the mid-ripening sweet persimmons ‘Shinshu’ and ‘Taishuu’ at Gyeongsangnam-do Agricultural Research and Extension Services. Line selection among the seedlings of ‘Shinshu’ and ‘Taishuu’ hybrids was carried out in 2014, and detailed characteristic investigations on fruit quality and tree growth were conducted from 2018 to 2019. ‘Olnuri’ matured around September 24, an average of 25 days earlier than ‘Uenishiwase.’ The tree is semi-upright, and only female flowers bloom. The trees bear oblate fruits with orange skin. The average weight of the fruit is 280 g, which is significantly higher than that of ‘Uenishiwase’ (190 g). The soluble solids content is higher and the firmness is lower than that of ‘Uenishiwase.’ There is almost no apex splitting or calyx end cracking. The marketable fruit rate is 80.0%, which is lower than that of ‘Uenishiwase’ (91.2%, data not shown). In the future, as a fully ripened persimmon in late September, ‘Olnuri’ is expected to play a big role in creating the sweet persimmon market during the autumn harvest period (Registration No. 8917).
