摘要: 采用常规根尖压片法对吉普赛女王(Gipsy Queen)、紫色情感(Purple Sensation)、奥德修斯(Odysseus)3个二倍体风信子品种进行核型分析,以分析不同品种间的进化程度和亲缘关系。结果显示,3个品种风信子的染色体形态比较一致,均由中部(m)、近中部(sm)着丝粒染色体组成,具1对随体,但随体分布存在一定的差异,其中Gipsy Queen的核型公式为2n=2x=16=6m+8sm+2sm(sat),Purple Sensation的核型公式为2n=2x=16=6m+2m(sat)+8sm,Odysseus的核型公式为2n=2x=16=6m+2m(sat)+8sm。3个品种的核型不对称系数分别为59.24%、58.92%、59.18%,核型类型均为2B类型。

Abstract: The karyotypes of three diploid hyacinth cultivars Gipsy Queen, Purple Sensation and Odysseus were analyzed by routine root tip pressing method to study the evolutionary degree and genetic relationship among different hyacinth cultivars. The results showed that karyotypes of hyacinths of three varieties were comparatively consistent, consisting of centromere chromosomes in the middle (m) and near-middle (sm), with a pair of satellites, but the distribution of satellites were differences in these three varieties. The karyotype formula of Gipsy Queen was 2n=2x=16=6m+8sm+2sm (sat), Purple Sensation was 2n=2x=16=6m+2m(sat)+8sm, and Odysseus was 2n=2x=16=6m+2m (sat)+8sm. The karyotype asymmetry coefficients of these three cultivars were 59.24%, 58.92% and 59.18%, respectively, and the karyotype types were all 2B.
