Abstract
A detailed karyotype analysis was carried out in five Korean native Iridaceae species; Iris pseudoacorus, I. pallasii. var. chinensis, I. tectrum, I. dichotoma and Belamcanda chinensis. Chromosome compositions of the five species showed that they have different karyotypic formulae; I. pseudoacorus 2n=34=10m+16smn+8st including two pairs of satellite chromosomes, I. pallasii var. chinensis 2n=40=26m+12sm+2st including two pairs of satellite chromosomes, I. tectrum 2n=30=14m+16sm including five pairs of satellite chromosomes, I. dichotoma 2n=32=22m+10sm including two pairs of satellite chromosomes, and B. chinensis 2n=32=20m+10sm+2st including one pair of satellite chromosomes. These results will supplement the previous cytogenetic reports in Iridaceae species and enhance our understanding on the genetic structure, which will be useful in clarifying the unique characteristics of each species for practical breeding programs for horticultural and pharmaceutical purposes.
