Which of the following benefits can be achieved through plant breeding technology in agriculture?
Increased crop yield
Improved crop quality
Increased resistance to pests and diseases
All of the above
Plant breeding technology involves the deliberate crossing of different varieties of plants to create offspring with desirable traits, such as increased yield, improved quality, and resistance to pests and diseases. This process is repeated over several generations, and the most promising plants are selected and further developed. This technology helps in the development of new crop varieties that can produce more food, resist pests and diseases, and adapt to different environmental conditions. In this way, plant breeding technology plays a critical role in ensuring food security and increasing agricultural productivity. Therefore, option 4 is the correct answer.
