| 摘 要： | 本文对浙贝Fritillaria thunbergii Miq．(取材于浙江鄞县和舟山)、东贝 F.thunbergii var．
chekiangensis Hsiao et K.C.Hsia和皖贝F.anhuiensis S．C.Chen et S．F.Yin的核型进行了分析比较，
其中东贝和浙贝(舟山)为首次报道．浙贝的核型：取材于浙江鄞县的为2n=24=4m(1sc) l)+4st(1sc)
+16t(1sc)，取材于浙江舟山为 2n=24=2m+2sm+12st(1sc)+8t(2sc)，东贝的核型为
2n＝24=2m+2sm+8st(2sc)+12t(4sc)，皖贝的核型为2n=24=2m+2sm+8st(2sc)+12t(5sc)。3个分类群均属3B核型。

| Abstract: | This paper deals with karyotype analysis of three taxa of Fritillaria, i. e. F.
thunbergii (from Yinxian and Zhoushan), F. thunbergii var. chekiangensis, and F. anhuiensis.
The results show that all the three taxa are diploid (2n = 24) and their karyotypes are differ-
ent. The karyotype formulae may be summarized as follows: F. thunbergii: Yinxian, 4m(lsc)
+4st(lsc) l) +16t(lsc) ; Zhoushan, 2m+2sm+12st(lsc) +8t(2sc) . F. thunbergii var.
chekiangensis2m+2sm+8st (2sc) +12t (4sc). F. anhuiensis 2m+2sm+8st (2sc) + 12t (５sc). There
are many secondary constrictions in all the three taxa of Fritillaria studied, but the numberand positions of secondary constrictions are quite different in different taxa. |
