%X We studied the karyotypes of five Itoh hybrid peonies by using squashing method. Five Itoh hybrid peonies were triploid(2<i>n</i>=3<i>x</i>=15). Asymmetry index ranged in 61.02%-62.41%, and the karyotypes of these cultivars were 2A. The karyotypes of the tested Itoh hybrid peonies were mainly made of median region, submedian region and subterminal region, without satellite. Our result provided cytological information and polyploidy resources for breeding research for the first time.
