Through principalcoordinate analysis, only a weak correlation between DNA fingerprints and the horticultural types of thespring orchid was observed. However, common alleles existed in cultivars from the same horticulturaltype, for example, 15 common alleles were found in the 3 cultivars of the colored flower type, and theCY2-J allele existed in the 43 cultivars of the plum petal type. All these cultivars, except for Longzi and LaoLongzi, could be distinguished from each other using these EST-SSR markers. Moreover, a set of 102 outof the 129 cultivars had their own specific alleles, and therefore, with a single EST-SSR marker, each ofthese cultivars can be distinguished from all other cultivars. These findings can be valuable for taxonomyimprovement as well as resource conservation and utilization, and the EST-SSR markers developed canalso be a useful tool for cultivar identification which is frequently required commercially.
