Somaclonal Variation and , Selection for Crop Improvementmation is started from proembryogenic masses on auxin-containing medium. Most likely, somaclonal variation originates from the exposure of dedifferentiated tissues to culture cycles; the degree and expression of the variation depend on the genotype and the genetic base of the species (Karp, 1995).

Genetic Fidelity of Plants Regenerated from Somatic Embryos of Cerealsated plants varied for a wide range of agro-morphological characters. The variability associated with cell and tissue culture has been termed ‘somaclonal variation’ by Larkin and Scowcroft (1981), which is defined as ‘the variation displayed amongst plants derived from any form of cell culture’.

Selection is the driving force of plant breeders to identify within a variable population the best genotypes which respond to the demands of agricultural producers, the agro-industry and consumers.

However, other types of variation arise by specific culture of cells or tissues, which include culture of: protoplasts (protoclonal); anthers and microspores (gametoclonal); callus (calliclonal); apical meristem (mericlonal); leaf, stem, root or other somatic tissues (somacl
