Variety traits
Matricaria recutita L.
The ploidy level of Matricaria recutita L. determines the morphological and biochemical properties of the plants, influencing flower head size, chlorophyll content, and flowering dynamics. Both diploid (2n=18) and tetraploid (2n=36) forms are used in breeding.
In the reference 17 varieties crop German chamomile, where this is mentioned in the description.
Wild forms of German chamomile are represented by diploid organisms with a chromosome set of 2n=2x=18, whereas breeding forms are often tetraploid (2n=4x=36). The ploidy level is determined using flow cytometry methods or by analyzing morphological markers, such as stomata size, pollen grain diameter, and the number of chloroplasts in cells.
The transition to the tetraploid level leads to an increase in the size of flower heads, leaves, and seeds, while altering plant architecture and flowering dynamics. Tetraploids often exhibit a later onset of flowering than diploids and are used in breeding to improve raw material quality indicators, including the content of essential oils and alpha-bisabolol.
