Abstract

Plant tissue culture was introduced as an asexual method to propagate plants rapidly and reliably. Many vegetable crops are propagated commercially in-vitro. India represents the second position in vegetable production having 162.19 million metric tonnes under 9.21 million hectares. 25-30%   vegetables are lost due to biotic (insect-pest, virus, fungi and bacteria) and abiotic stresses (draught, flooding, salinity and extreme of temperature). So, for the enhancement of vegetable production somaclonal variation is a universal feature of plant tissue culture, a method whereby plant parts are grown on artificial medium. Stress tolerant plant is developed by the help of tissue culture that changed the physiology and biochemical of plants which is genetically stable and helps in crop development. Somaclonal variations occur in rather high frequencies, which is a great advantage over conventional mutagenesis. Use of somaclonal variation may reduce the time required for the release of new variety as compared to mutation breeding.
