Abstract: Chromosomes from root tips of Lilium speciosum Thunb.var.glorosoides Baker were analyzed by Giemsa Cbanding. The results shown that, the karyotype is 2n=24=8C+4CI++2CI++2CN+4I++2I+T++2, the banding number of haploid genome was 20. Strong banding were observed on the centromeric place of chromosome A, E, H, J, K, and short arm of chromosome F. Chromosome A is SATchromosome, and strong banding were observed on the secondary constriction. Three different intensity bandings were shown on the short arm of chromosome B. Each chromosome of Lilium speciosum Thunb.var.glorosoides Baker could be distinguished by Giemsa Cbanding. The Cbanding results derived from this study provided reliable evidence for the identification of hybrid and the chromosomal location of the interesting genes.
