Chrysanthemum [ C. × grandiflorum Tzvelv. (= C. × morifolium Ramat.)] is a valuable ornamental and commercial crop, and ≈20,000–30,000 cultivars have been developed date ( Zhang and Dai, 2013 ). The outer ray florets and inner disc florets

The chrysanthemum (Dendranthema grandiflora Tzvelev.) cultivars `Dark Charm', `Salmon Charm', `Coral Charm' and `Dark Bronze Charm' are either radiation-induced mutants or spontaneous sports of `Charm' and constitute a family or series of plants that primarily differ in flower color. These cultivars, which were difficult to differentiate genetically by DNA amplification fingerprinting (DAF), were easily identified by using arbitrary signatures from amplification profiles (ASAP). Genomic DNA was first amplified with three standard octamer arbitrary primers, all of which produced monomorphic profiles. Products from each of these DNA fingerprints were subsequently reamplified using four minihairpin decamer primers. The 12 primer combinations produced signatures containing ≈37% polymorphic character loci, which were used to estimate genetic relationships between cultivars. Forty-six (32%) unique amplification products were associated with individual cultivars. The number of ASAP polymorphisms detected provided an estimate of the mutation rate in the mutant cultivars, ranging from 0.03% to 1.6% of nucleotide changes within an average of 18 kb of arbitrary amplified DAF sequence. The ASAP technique permits the clear genetic identification of somatic mutants and radiation-induced sports that are genetically highly homogeneous and should facilitate marker assisted breeding and protection of plant breeders rights of varieties or cultivars.

Several crop species (e.g., cut chrysanthemum) can only be grown year-round in colder climates when cultivated in heated greenhouses. This implies that production during autumn and winter will require high energy inputs, and therefore energy
