Genetic manipulation is a process of transferring of desirable characters (genes) from one plant to another plant. This is done for production of varieties with desirable characteristics like profuse branching in fodder crops, high yielding varieties in maize, wheat, etc.

Genetic manipulation is useful in developing varieties which have increased yield, better quality, shorter and early maturity period, better adaptability to adverse environmental conditions, well as desirable characteristics. Agricultural practices of cultivation and yielding of crops are directly related to agronomic conditions. These conditions are based on weather, soil quality and availability of water resources. Since weather conditions are unpredictable such as drought and flooding situations, therefore, crop varieties have been developed that can be grown in diverse climatic conditions.
