INTRODUCTION

The breakthroughs in science that permitted genes and thus heredity, to be identified and manipulated as molecules ushered in the biotechnology era, which is now more than two decades old. The new tools of biotechnology are changing the way scientists can address problems in the life sciences; agriculture is one area facing major changes as a result of this new technology. The unanticipated rapid rate at which discoveries and their applications in biotechnology have unfolded has stressed the capacity of society more specifically, our agricultural research and educational institutions to absorb and adjust to change. We are challenged by pressing decisions, opportunities and problems that we face now and will continue to face in the future. Competition from abroad impels us to devise and use new technologies that can improve the efficiency and quality of Indian agricultural production. Securing a better life for our citizens where each one of us, can lead lives of dignity and fulfillment therefore merits undivided attention in our development strategy. A natural corollary to this is the attainment of the goal of food security for all. The per capita availability of land has also been shrinking due to population increase and this has been compounded by increase of wasteland. There is also spread of urbanization and the growing demand for more land. We are left with a situation where we have to produce more from the limited land available to ensure food security. But in doing so, we must always keep in mind that any food production and consumption policy must safeguard that the integrity of natural eco-systems is not compromised.
