Morphological and molecular characterization of some Chrysanthemum (Dendranthema grandiflora) cultivars
Year: 2024

Abstract: The diversity and genetic relationships among seven commercial chrysanthemum cultivars were analyzed using morphological and molecular markers. Vegetative growth, flowering, flower yield, and flower quality parameters were evaluated to assess genetic variability across the cultivars. Cultivars Crystal Red, Kodiack, and Crystal White exhibited superior vegetative growth, while Abrun, Crystal Red, and Kodiack displayed better flowering characteristics, particularly in terms of the number of inflorescences per plant and mass of colored flowering. Crystal White, Coca Bleach, and Crystal Red cultivars demonstrated the highest inflorescence stalk length, while cvs. Crystal Red, Crystal Yellow, Crystal Pink, and Kodiack Yellow recorded the maximum number of ray floret inflorescences. Other quality parameters such as inflorescence diameter and ray floret length were found to be optimal in Kodiack, Crystal White, Crystal Pink, Coca Bleach, and Crystal Yellow cultivars. Simple Sequence Repeat (SSR) markers were employed to distinguish and identify standard-type chrysanthemum cultivars, utilizing twelve SSR markers from the chrysanthemum SSR database. The results suggest that these SSR markers hold promise for identifying additional chrysanthemum cultivar types and assessing genetic relationships among them. Association studies combining morphological and molecular data offer a valuable approach to identifying informative markers for plant breeding purposes.
