The variety Roland is characterized by fungitoxic activity against Fusarium oxysporum f. sp. dianthi, which is due to the presence of flavonoids, such as datiscetin, in the plant tissues. The plant possesses high resistance to fungal diseases.
Studies of post-harvest characteristics note that flowers of the variety Roland retain freshness for a long time after cutting and do not release ethylene during senescence. The variety has limited distribution in commercial catalogs and is more often mentioned as a subject of breeding research.
