Abstract: Using Lagerstroemia caudata as comparison, L.fauriei, L.limii,L. speciosa, L. indica ‘Dynamite’ and 12 interspecific hybrids between L. indica and L. speciosa were diploid by detecting with flow cytometry. Eight SSR markers were used to determine the ploidy of Dynamite, L. speciosa, L. limii and 26 interspecific hybrids between L. indica and L. speciosa, and these plants were diploid. These results confirmed the feasibility of flow cytometry and SSR markers to reflect plant ploidy.

Key words: Lagerstroemia indica, Lagerstroemia speciosa, interspecific hybridization, flow cytometry, SSR, ploidy
