Biotechnology of floricultural crops-scientific questions and real world answers. The food and fiber requirements of approximately 10 billion people need to be met with existing resources that are currently limited. Three Research Groups in Delhi perform plant research to devise ways to improve food production and nutritional yield. A critical requirement for crop improvement is the introduction of new genetic material into the cultivated lines of interest, whether via single genes, through genetic engineering, or multiple genes, through conventional hybridization or tissue culture techniques. and Cornish, E.C. Fruit-specific RNAi-mediated suppression of DET1 enhances carotenoid and flavonoid content in tomatoes. and Srinives, P. (2006). Modification in the genetic make-up of crops may be expected to be quite rewarding in the future. • The risks and benefits of genetic crop improvement are associated with the particular changes that have been introduced, not the method by which they were introduced. Thus, a major goal of plant scientists is to find ways to maintain high productivity under stress as well as developing crops with enhanced nutritional value. Van der Krol, A.R., Lenting, P.E., Veenstra, J., van der Meer, I.M., Koes, R.E., Gerats, A.G.M., Mol, J.N.M. • All genetic crop improvement methods rely on introducing genetic changes.
