Agricultural biotechnology has emerged as a transformative force in modern crop improvement, offering unprecedented opportunities to enhance food security, nutritional quality, and agricultural sustainability. This research article examines the current applications of biotechnology in crop development, including genetic modification, marker-assisted selection, gene editing technologies, and tissue culture techniques. The study analyzes the opportunities presented by these technologies in addressing global challenges such as climate change, population growth, and malnutrition, while also examining the associated challenges including regulatory frameworks, public acceptance, and ethical considerations. Findings indicate that biotechnology holds significant promise for revolutionizing agriculture, though successful implementation requires careful consideration of scientific, social, and economic factors.
