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.
