Biotechnology and agricultural improvement

A range of emerging technologies are expected to play a significant role in agricultural improvement in the next 20 years. Some are only now being explored, but others have already produced significant results. Recent progress in the tissue culture and genetic engineering of crop plants has opened the door to: (1) large scale and rapid propagation of genetically uniform plants from elite materials; (2) the selection of novel and improved varieties using somaclonal variation technology; (3) the development of new hybrids between different cultivars and species by means of protoplast fusion and (4) the use of recombinant DNA to introduce new genetic material into plant cells. It is expected that, by the year 2000, a wide range of crops will be affected by these advances in biotechnology.
