Background : The most problematic disease in Boxthorn is Anthracnose. New variety with Anthracnose-resistant is good for high yield and Safe fruit production in open field. Therefore it is necessary to develop a New variety with Anthracnose -resistant and high yield. Methods and Results : The new boxthorn line, CB10511-104 was selected from the cross between Cheongun (IT232599) and CB08456-113 to breed new variety with high yield and Anthracnose-resistant in 2011. Its preliminary yield test was performed from 2012 to 2013 and the selected line was named Cheongyang 25. Its regional yield trials were carried out in Cheongyang, Yesan and Jindo for 3 years, from 2014 to 2016. Cheongyang 25 was registered as the new variety, Cheonggeum, in 2016. The specific characteristics were summarized as follows; Tree shape is open type and the leaf is round-lanceolate. The flowers are normal size and purple.

Anthracnose on fruits in open field was slightly similare compared to the check variety, but check variety was Anthracnose-resistant. The content of betaine and free sugar in dried-fruits were higher than that of the check variety. The dried-fruit yield was decreased about 17 percent in open field.
