Karyotype analysis of Lilium lancifolium and four related cultivars
Keywords:Lilium lancifolium, cultivars, karyotype, chromosome
Lilium lancifolium is one of the most important species of genus Lilium. Besides ornamental value, it also has highly edible and medicinal properties. We investigated the karyotypes of L. lancifolium and four related cultivars. The results indicated that the ploidies of four cultivars varied from diploid to tetraploid. Both ‘Flore Pleno’ and ‘Red Velvet’ were triploid (2n=3x=36), consistenting with the wild species L. lancifolium. ‘Sweet Surrender’ was diploid (2n=2x=24), and ‘Red Life’ was tetraploid. All karyotypes of candidates belonged to 3B type except ‘Flore Pleno’, which belonged to 3A type. Karyotype symmetry analysis revealed that the wild species L. lancifolium had a middle value of A1, A2, and TF%, which meant that the cultivars related to L. lancifolium had different tendencies to symmetry compared to L. lancifolium, but whether they were higher or lower was unclear.
