genetic studies have been mainly focused on interspecific diversity within the genus Cucurbita or genetic diversity among C. pepo subspecies with an emphasis on other cultivar groups ( Ferriol et al., 2003 ; Formisano et al., 2012 ; Gong et al., 2008

cultivars accounted for >95% of the acreage used in tuber production ( Bell et al., 1998 ; Deng et al., 2005c ). As a result, there is increasing concern over the loss of genetic diversity in caladium via loss of cultivars. Similar concerns have been raised
