WebIntroduction: Colchicine is a toxic chemical that is often used to induce polyploidy in plants. Basically, the colchicine prevents the microtubule formation during cell division, thus the chromosomes do not pull apart like they normally do. The end result is a cell that now has double the number of chromosomes that it would normally have.

A diploid plant can become polyploid due to a disruption in mitosis or meiosis. It can and does occur in nature, but is also induced by using chemicals like colchicine. A polyploid plant has many potential advantages over a diploid plant, and this Gardenerdy article presents a list of them. Webvitro is an effective method to induce polyploidy, which could increase the efficiency of recovery of polyploid plants and reduce the incidence of chimeras (Compton et al., 1996; Chakraborti et al., 1998).
