Plant breeding and genetics have revolutionized modern agriculture, offering sustainable solutions to global food security challenges. Recent advancements in molecular genetics, genomic tools, and biotechnological innovations have accelerated the development of high-yielding, stress-tolerant, and disease-resistant crop varieties. This manuscript explores the pivotal role of plant breeding and genetic research in addressing climate change, resource scarcity, and biodiversity conservation. Key innovations such as marker-assisted selection, CRISPR-Cas9 genome editing, and genomic selection are highlighted, along with their applications in crop improvement programs. The integration of advanced breeding strategies with traditional knowledge holds immense potential for achieving global agricultural sustainability.
