Abstract
We surveyed 14 selected populations of Rubus coreanus Miq. that are indigenous to Korea, examining the leaves, fruiting laterals, and fruits, in order to develop superior cultivars of this species. Whereas most of the populations in the Songgye region had large leaf characteristics, populations in the Hannam, Sanghyo, Wonju, and Chiak regions generally had small leaf characteristics. The Songgye region plants also had longer leaves relative to their leaf widths. The number of flowers and number of fruits per fruiting lateral were 19.7 and 19.8, respectively, for the Gochang region, and 19.3 and 18.9, respectively, for the Hannam region. Both these regions exceeded the average numbers of flowers and fruits, which were 17.2 and 16.6, respectively. There were wide variations in fruit length, width, weight, and morphological characteristics. A principal components analysis (PCA) of 24 characteristics revealed that the first principal component value was 9.53 (or 39% of the total variance), the second principal component value was 5.85 (24.3% of the total), the third principal component value was 3.53 (14.7% of the total), the fourth principal component value was 2.00 (8.3% of the total), and the fifth principal component value was 1.20 (5.0% of the total). The proportions of the top five principal components accounted for a high percentage (92.2%) of the total variance.
