文摘内容 Several sequences were applied to resolve phylogenetic relationships within Dendranthema and clarify the origin garden chrysanthemums including sequences of nrDNA ITS,trnT-trnL and trnL-trnF intergenic spacer regions in cpDNA.The relationships among the species are so close that the three sequences could only provide limited information. Form the evidence presented,we suggest that:①D.lavandulifolium might be the chloroplast donor of D.vestitum(HN)with the resembling morphology and the same trnT/L IGS sequence.②D.vestitum,a putative ancestor,may be not the chloroplast donor of garden chrysanthemums.D.lavandulifolium migth be the chloroplast donor of the type population of D.indicum(HN)or the direct.chloroplast donor of the ancient garden chryanthemum cultivar.③D.zawaskii might be not the ancestor of garden chrysanthemums。
