  • The Karyotypes of Korean Sciurus uulgaris coreae and Tamias sibiricus asiaticus were analyzed by the G-banding method. Chromosomes of two species could be identified by G-banding patterns. The banding patterns of chromosomes 9, 10, 12 and X of S. vulgaris coreae were identical to those of chromosomes 6, 9, 12 and X, respectively of T. sibiricus asiaticus. It was shown that chromosomes 4, 10, 7 and 17 of T. sibiricus asiaticus resulted from pericentric inversion of chromosomes 1, 7, 8 and 16 of S. vulgaris coreae. These results suggested that pericentric inversion was an important factor in the karyological differentiation of two species.

  • The chromosomal analyses of Dendmcopos major hondoensis and D. leucotos Ieucotos(Picidae:Piciformes) in Korea were performed by conventional Giemsa staining and C-banding method. The diploid number of two species was 2n=90-92 and arm number was AN= 92-96.The conventional karyotypes were very similiar but distribution of constitutive heterochromatin were differ in the first chromosome. The second and several pairs of macro-telocentric chromosbmes have telomeric constitutive heterochromatin.

  • Chromosome analysis using karyotyping and bicolor FISH were carried out in Pimpinella hallaisanensis which is one of the endemic plants in Jeju island of Korea. The somatic methaphase chromosomes number of this plant was 2n=2x=22 and the size of this chromosomes ranged from 3.58 to $5.82{\mu}m$. The chromosome complements consisted of two pairs of metacentrics (chromosomes 1 and 2), four pairs of submetacentrics (chromosomes 3, 4, 6 and 8) and five pairs of subtelocentrics (chromosomes 5, 7, 9, 10 and 11). Using bicolor FISH, three pairs of 5S and four pairs of 45S rDNA loci were observed. Two pairs of 5S rDNA signals were detected on the end of the long arm of chromosome 4 and one pair of them were observed between long arm end and centromere. Another 45S rDNA signals were detected on the end of short arm of chromosome 4, 6, 10 and 11, respectively. Hence, the chromosome number reexamined using both conventional staining and FISH methods was different from previous report.

  • The karyotype of F. velutipes Korean cultivar, Fv 3-6, was compared with those of Japanese cultivars, Fv 0-1, Fv 1-5, Fv 11-1, by CHEF gel electrophoresis. The Korean cultivar, Fv 3-6, showed the difference from the three Japanese cultivars in number and size of chromosomes; the Fv 3-6 had two and one more chromosomes then Fv 0-1 and Fv 11-4, and Fv 1-5 had, respectively. The karyotyping by CHEF gel electrophoresis is quite suitable to define new Korean cultivars against Japanese cultivars.

  • The karyotype of the Niwaella multifasciata, endemic species to the Nakdong River in Korea, is reported for the first time. The sample species, Niwaella multifasciata collected from the Milyang River and the Nam River which are tributaries of the Nakdong River, has a diploid complement of 50 chromosomes composed of 10 metacentric, 28 submetacentric, 12 subtelocentric chromosomes, and 88 arm numbers. The arm number of Niwaella multifasciata was larger than any other species of Cobitidae. Sexual dimophism and intraspecific polymophism of the chromosomes were not observed in this study.

  • The karyotype analysis of Liobagrus somjinensis, an endemic Korean freshwater fish with restricted waters and a new species of torrent catfish was carried out from nine females and eight males of Somjingang River, Sikjeong-dong, Namwon-si, Jeollabuk-do, Korea. The diploid number of chromosomes was 42, and its karyotype was composed of 28 metacentrics and 14 submetacentrics; 84 FN (fundamental number). Polyploidy and sex dimorphism were not observed in the present species. The chromosome number of L. somjinensis was the same as its congeners, but there was a difference in karyotypes.

  • The chromosome numbers of two species (Culter brevicauda and Erythroculter erythropterus) of Korean Cultrinae are investigated. In two species, the mitotic chromosomes from 24 groups with two chromosomes each indicated that it is a diploid. Their karyotypes and total length of chromosomes were slightly different from each other. The karyotype of C. brevicauda and E. erthropterus is 2n=48 (7M+10SM+7ST), FN=96 and 2n=48 (6M+10SM+8ST), FN=96. Observed chromosomes of C. brevicauda and E. erythropterus ranged from 5.4 to $2.2{\mu}m$ and 6.1 to $2.3{\mu}m$ in length, respectively.
