However, common alleles existed in cultivars from the same horticultural type, for example, 15 common alleles were found in the 3 cultivars of the colored flower type, and the CY2-J allele existed in the 43 cultivars of the plum petal type.
All these cultivars, except for Longzi and Lao Longzi, could be distinguished from each other using these EST-SSR markers.
Moreover, a set of 102 out of the 129 cultivars had their own specific alleles, and therefore, with a single EST-SSR marker, each of these cultivars can be distinguished from all other cultivars.
