Karyotype analysis of somatic chromosome was attempted to find out the relationship among the 3 species of Abies growing in Korea, and A firma introduced from Japan The results were summarized as follows: 1) The number of somatic chromosome was equal for all species, 2n=24. 2) When somatic chromosome was arranged by descending order of the short arm length, the long arm of number 9 chromosome of A. holophylla was much larger than that of the other species. A. koreana and A. nephrolepis had a similarity in b/a value and A. holophylla and A. firms were also similar. 3) When it was arranged by descending order of the short arm length, eight chromosomes of A. koreana and A. nephrolepis showed a similar in b/a value, and two chromosomes of A. holophylla and A. firms did in its value. 4) When it was arranged by descending order of total length, chromosome numbers 7 and 8 in A. koreana were particularly similar to those in A. nephrolepis. 5 ) When it was arranged by descending order of total length, six somatic chromosomes of A. koreana and A. nephrolepis were similar in b/a value, and two somatic chromosomes of A. holophylla and A. firma similar in its value. 6) When it was arranged by descending order of long arm length, in the of b/a value of chromosome number one in A. koreana and A. nephrolepis was much larger, and that in A. holophylla and A. firms was much smaller than that in the others.
