Abstract

Phylogenetic relationship of lilium plants was studied by means of trnH-psbA DNA barcode technique. The result demonstrated that trnH-psbA sequence length varied in different lilium plants. The entire length of trnH-psbA sequence was 460 bp after multiple alignments. The number of conserved sites was 415 and that of variable sites was 45. A total of 63 tested materials were clustered into five groups. Lilium davidii, 7 Asiatic cultivars, one cross progeny between Asiatic cultivar and wild parental species, were clustered into one subgroup (the Ⅰa subgroups). Lilium speciosum var. gloriosoides, 10 Oriental cultivars and 2 intra-section Archelirion cross progenes were gathered into one subgroup (the Ⅰb subgroup ). Majority of the tested wild species were clustered into the Ⅱ group which showed the characteristics of intra-species and geography. To some extent, the phylogenetic relationship of wild lilies in Ⅱ group via trnH-psbA barcode was inconsistent with the result obtained from traditional morphological classification method. The other 4 Asiatic cultivars and one cross progeny between one Asiatic cultivar and wild parental species were clustered into the Ⅲ group. Therefore, the Asiatic cultivars in Ⅰb subgroup and those in the Ⅲ group were originated from different lilies in the section Sinomartagon.
