Crop Improvement: New Approaches and Modern Techniques

With the increasing volume of world, population there is relative increased demand of food. Conventional breeding methods no more remain viable to overcome this situation. The field of biotechnology and molecular biology revolutionize the agriculture and farming methods. In this review we discus some molecular approaches and biotechnology tools for the production of new plant varieties. Plants resistant to biotic and biotic stress tolerant to drought or other harsh environmental conditions had produced. A number of techniques including tissue culture mutagenesis, transformation have been used. Advance functional genomics studies give better understanding of plant genome and help in modifying it. RNA interference, next generation sequencing and nanotechnology have become a new promising technique for improving crop according to future need.
