‘Yedasol’: A Cultivar of Multi-Stem Korean Red Pine (Pinus densiflora f. multicaulis Uyeki) with Conical Crown Form

Multi-stem Korean red pine (Pinus densiflora f. multicaulis Uyeki) is known as the forma of Korean red pine and is distributed in both Korea and Japan. Unlike Korean red pine having one or two main stems, it grows with many stems which are branched from the lower part of the tree trunk. Owing to its unique stem shape and ornamental value, it has been used as a precious ornamental tree. A total of 14 individuals with distinct characteristics were collected between 1998 and 2000 to develop new cultivars in Pinus spp. with high added value. After asexual propagation through grafting, at least 20 seedlings per tree were planted in a test field and the phenotypic characteristics were investigated. Based on the results, three individuals were re-selected and tested for uniformity and stability for 3 years. Finally, one individual with evident conical crown form was renamed as ‘Yedasol’ and was registered as a new cultivar in 2021. In addition, ‘Yedasol’ has high ornamental value derived from its thinly cracked gray-brown bark, soft needle leaf, reddish-purple male strobilus, and dense cone arrangement (Registration No. 255).
