Plant breeding is a method of breeding plants to achieve desired characteristics such as superior quality, high yield, and disease resistance. The growing population is a big concern. The main challenge here is to meet the increased demand for resources. The Green Revolution, came up with the idea to increase the production of food to meet the population's requirements. To make the Green Revolution a success, modern methods and technologies were used, like the use of fertilizers, pesticides, high-yielding seeds, irrigation facilities, etc. High-yield varieties of wheat and rice have greatly contributed to the increase in food grain production. The main objective of plant breeding is to increase yield, improve quality, increase tolerance to environmental stress, and increase resistance to various pathogens and pests. Governments and various companies run plant breeding programs worldwide.
