Abstract
Somatic chromosome numbers of 19 taxa of Korean Rubus was investigated. Subg. Anoplobatus (2 species), subg. Cylactis (1 species), subg. Idaeobatus (15 taxa) and subg. Malachobatus (1 species) are found in Korea. All taxa belonging to subg. Idaeobatus except for R. parvifolius which shows tetrapolid and hexaploid are diploid. The basic chromosome number of the genus was x=7. New chromosome numbers for 5 taxa were reported here: R. hongnoensis of Jeju-island endemic species, 2n=14; R. longisepalus, 2n=14; R. longisepalus var. tozawai, 2n=14; R. parvifolius, 2n=28; R. parvifolius var. taquetii, 2n=28. The rest 12 taxa except for R. coreanus Miq was well counted as 2n=14 and well consistent with previous reports from China and Japan. Our new chromosome level for R. parvifolius as 6x may indicate that speciation by polyploidization has occurred within Korean population. Unlikely to Japanese population (2n=42), Korean population of R. buergeri has same ploidy level with Taiwanese population as 2n=56.
