Giemsa C-banding Analysis of Root Tip Chromosome in Lilium dahuricum

In this paper,we analyzed the root tip chromosome of Lilium dahuricum Ker-Gawl. by employing Giem-sa C-banding approach. The results showed that there were abundant chromosomal ploidy variation ploidy variation in tube-cultured plantlet of Lilium dahuricum,and the chromosomal ploidy variation included diploid (2n=2×=24),triploid (2n=3×=36),tetraploid (2n=4×=48) and hexaploid (2n=6×=72). Result of the diploid Lilium dahuricum Ker-Gawl C-banding research were analized. The C-banding karyotype of diploid Lilium dahuricum was 2n=2×=24= 2CI++2CI+T+T++6I+2I++2I++2I+T++2I+T++2I+T++2T++2T+,and each chromosome had their own unique band pattern dis-tinguishable from each other. Strong bands were mainly distributed on both the long arms and the short arms. Each chromosome of Lilium dahuricum Ker-Gawl can be distinguished by Giemsa C-banding.
