초록 | Chrysanthemum represent the second most economically important cut flower after rose, in the global market trade. It’s phenomenal importance and global popularity, gained increased breeder’s attention, resulting in the release of huge number of cultivars. Identifying the cultivars is crucial to protect the breeder’s intellectual property rights and to improve the efficiency of breeding. Distinguishing chrysanthemum genotypes based on the morphological characteristics is challenging as they highly vary within the group and hence requires efficient molecular markers. Here, we evaluated the genetic diversity of 57 spray type chrysanthemum cultivars bearing white, ivory and cream colored flowers. A total of 6 loci were evaluated for their polymorphism efficiency across the tested cultivars. Number of alleles ranged from 2 to 6 with a mean of 3.5 alleles per locus. Average polymorphism information content (PIC) was 0.53 for 6 SSR markers. Cluster analysis of genetic relationship by UPGMA method revealed a genetic distance of 0.31 to 1.00 and the 57 white-variants of chrysanthemum cultivars were discriminated by the tested SSR markers. However, 2 sets of cultivars including Pure Angel: Neba and Ladost: White wing showed complete genetic similarity and could not be discriminated. These results provide efficient SSR markers that can assess the genetic relationship and identification of chrysanthemum cultivars which cannot be discriminated based on phenotype. |
