Somaclonal variation is defined as genetic variation observed among the progeny of plants regenerated from somatic cells culturedin vitro. Although theoretically, all plants regenerated from somatic cells should be clones, a number of observations have indicated that this is not the case. In addition to the basic genetic implications of this phenomenon, the variation has proven useful in breeding programs of various crop plants.

Thus during tissue culture arising from a clone is not always the case, sometimes a variant can be obtained.
