Abstract: Artificial chromosome doubling in vitro is an efficient approach to produce polyploidy plants. This paper reviews advances in in vitro induction of autotetraploids in plants. It compares methods and the influence of chromosomal manipulation in vitro as well as different chromosome-doubling inhibitor capacities and introduces the identification of the different ploidy levels in early in vitro regeneration. It also discusses the potential of obtaining polyploidy plants through in vitro induction.

Key words: Autotetraploid, In vitro, Chromosome-doubling
