Impact of transgenic crops on sustainable agriculture – A review

The crop, which has got alien genes into its cells by recombination DNA technology, is called transgenic crop. These crops are used for many purposes: improve the quality of the agricultural or horticultural products; such as, tolerance to cold, frost, or drought, the resistance of plants to insects and diseases. Improving resistance to these diseases and insects also reduces the need of herbicides and pesticides. This makes the plants safer for the environment. In the future, transgenic crops may play the pivotal role for developing country with respect to food and nutritional security. Now, this is the only alternative available to cope up with the burgeoning population. The GM crops offer both challenges and opportunities for growth and development of mankind. These technologies should be used to complement the traditional methods for enhancing productivity and quality rather than to replace the conventional methods.
