Somaclonal variation can be termed as the appearance of variation among the clonally achieved somatic cells. The variations among the somatic cells are of phenotypic as well genotypic in nature. Most of these variations are the results of significant changes in cytoplasmic or nuclear genetic elements such as aberrations in chromosomal number, morphology. Some of the most important factors responsible for this phenomenon in plant system are regeneration system, type of tissue, ex-plant source, media components and culture cycle duration. Specially, the in vitro cultured plants form variants in stressful culture conditions. This phenomenon is highly undesirables when the target is to achieve identical true to type plants. But it can be a boon for producing desirable mutant genotypes which may prove to be economically more viable than a normal plant type. Somaclonal variations has been utilized in several ornamental plants such as Chrysanthemum, Coreopsis, Petunia, Phalaenopsis, Gladiolus etc. Even though, somaclonal variations sound promising but due to unpredictability and uncontrolled nature variations and unstable inheritance in the plant progenies have ceased this technology into narrower level of application.

Key words: In Vitro, Somaclonal Variation, Ornamentals Plants, Plant Tissue Culture.
