Plant Genetic Resources(PGR) are essential to our life and human being depends on PGR for all his or her conveniences, clothes, foods, houses and emotion etc. Historically, the principle of common heritage of mankind was prevailed in international practice on PGR. But, that concept has shifted from the common heritage of mankind to the principle of national sovereignty and common concern of humankind since the adoption of Convention on Biological Diversity(CBD). This article aims at the introduction of alternative solutions for access to plant genetic resources and benefit-sharing of that use. So, this article review the international conventions on plant genetic resources, which are International Undertaking on PGR, International Treaty on Plant Genetic Resources for Food and Agriculture, Convention on Biological Diversity, Bonn Guidelines, International Convention for the Protection of New Varieties of Plants(UPOV Convention) and Trade-Related Aspects of Intellectual Property Rights Agreement(TRIPs Agreement).
