Abstract
The new Rubus coreanus Miq. variety, ‘Doo-Ryun’, was selected from 227 clones of the clone bank. This breeding was progressed to select the superior variety for high productivity from 1998 to 2005. To evaluate the clones, characteristics of a fruiting lateral and a ripe fruit were investigated. ‘Doo-Ryun’ was finally selected through selection of three times and stable trial at four different regions. ‘Doo-Ryun’ has specific morphological characteristics that are fewer thorn in lateral and strong glossiness of leaf upper side than contrast clone. The flowing and fruiting characteristics of ‘Doo-Ryun’ shown that the number of flower per fruitng lateral, the number of fruit per fruiting lateral, fruit weight and yield per individual were 17.2, 16.9, 1.73g and 4.50kg, respectively. Also, their selection effects were evaluated as 103.6%, 107.6%, 140.6% and 155.7% compared to the mean of whole clones in the clone bank, respectively.
