With the increase of national and intenmtional exchange of plant germplasm, the potential risk involved in distribution of plant pathogens, especially plallt viruses in previously unaffected areas has increased. Realising the Heed for developing an efficient system for maintaining and exchanging virus-free germplasms work has been initiated at National Plant Tissue Culture Repository of NBPGR. The strategy for production of virus-free germplasm is discussed in this brief review.
