✦ Synopsis

Sporting is a well known phenomenon in chrysanthemum and a process by which new cultivars may arise vegetatively from the parental cultivar . A group of cultivars formed this way is called a family of cultivars . Mutations or cell layer rearrangements may be involved . In chrysanthemum there are three different cell layers that form different parts of the plant . Since the species is chimeric these cell layers may be genetically different . Differences at the DNA level among cultivars within one family and among the layers of one cultivar were studied by a PCR-based technique named RAPD analysis . Polymorphisms between cultivars as well as between different cell layers have been observed .
