Celosia argentea L., Amaranthaceae, is an annual herb cultivated for its medicinal, nutritional and horticultural values. It is rich with minerals, proteins, vitamins and several other compounds such as saponins, alkaloids, peptides, glycosides, flavonoids, amino acids and fatty acids. Medicinal properties of this plant are applied in traditional medicine to treat tumors, jaundice, fever, diarrhea, inflammation and various other diseases. As an ornamental plant it is particularly grown for its flowers. Somatic induced polyploidisation in vitro is one of the methods used in breeding programs of ornamental plants. Chromosome doubling usually increases plant vigour and enhances morphological traits like flower shape and size.
