A variety or variety produced from a plant cell or tissue is called somaclonal variation or somaclonal variation. Clonal variation arising from vegetative gametes is called gametoclonal variation. In tissue culture technology, superior and superior clones are selected by creating somaclonal variation. Numerous new cultivars were then created from the clones. Somaclonal variation has led to the creation of economically important plant cultivars, disease resistant varieties, pesticide resistant plants, drought resistant plants and herbicide resistant plants. Improved varieties of wheat produced through semiclonal variation are AdhI.
