Healthy sugarcane plants can be obtained from diseased plants by meristem culture. Although the plant is virus infected, the apical and axillary meristem is free of virus. The meristem is removed from the plant and grown in vitro by micropropagation. THe plants produced are virus free. Large number of plants are produced in a very short duration. The plants are genetically  identical known as somaclones. Nutrient medium rich in sucrose inorganic salts, vitamins, amino acids and growth regulators like auxins, cytokinins etc. is provided. The plants produced are virus free.                                                                                                                                             3 mark
