Abstract :
On the basis of karyebpic analysis performed by conventional staining and Giemsa C-banding technique, cytological relationship was inferred for 21 lines of Paeonia lactiflora Pal. cultivated in Korea. It was very difficult to infer their organized karyebpic classification system using the composition of somatic chromosomes involving sat-chromosomes, relative length of chromosomes, arm ratio and karyobpic formulae by conventional staining. From the distribution and number of Giemsa C-bands on the chromosomes b and c, 21 lines can be subclassified into 5 groups. It seems that the karyebpic polymorphism is observed in 21 lines of cultivated P. lactiflora because peony mainly propagates by outbreeding.
