| Abstract: | The present paper deals with a comparative karyotypic study of three species in Fri-
tillaria-F. thuncergii Miq., F. anhuiensis S. . Chen et S. F. Yin and F. hupehensis Hsiao et
K. C. Hsia. The karyotype of F. anhuiensis S. C. Chen et S. F. Yin is first reported.
The karyotypes of the three species of Fritillaria are rather similar, all with K(2n)=24=
2m+2sm+12t+4st+4m (SAT), showing a close interspecific relationship. They all have two
pairs of st chromosomes, one of which is the third chromosome in all the three species studied,
but the other is the seventh in F. thunbergii Miq, the eighth in F. anhuiensis S. C. Chen et S. F.
Yin, and the fifth in F. hupehensis Hsiao et K. C. Hsia. It tells us that there are some differences
in their karyotypes. All of the three species possess two pairs of satellite chromosomes with the
satellites located on the long arms. A heterochromatic zone is found sometimes on long arms of No.
IX chromosome in each species of Fritillaria and on one of No. I chromosomes in both F. thun-
bergii Miq. and F. anhuiensis S. C. Chen et S. F. Yin, a chromosome polymorphism occurring
between populations of Fritillaria. In addition, three B chromosomes are always found in most
root-tip cells of F. hupehensis Hsiao et K. C. Hsiao. |
