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.
