What is genetic manipulation? How is it useful in agricultural practices?

Explanation

Genetic manipulation is a process of transferring genes (characters) that are desirable 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 and other such 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 water resources availability. Since weather conditions are unpredictable such as drought and flood situations, therefore, crop varieties have been developed that can be grown in diverse climatic conditions.
