MOLECULAR BREEDING VS. GENETIC ENGINEERING: A COMPARATIVE STUDY IN CROP IMPROVEMENT

Crop improvement is crucial for ensuring global food security and sustainability. Molecular breeding and genetic engineering are two advanced biotechnological approaches that have revolutionized agriculture. This paper provides a comparative analysis of molecular breeding and genetic engineering, exploring their methodologies, advantages, challenges, and applications in crop improvement. While molecular breeding enhances natural genetic variation through marker-assisted selection (MAS), genetic engineering enables precise gene modifications using recombinant DNA technology and CRISPR-based genome editing. The study highlights case studies, regulatory frameworks, and public perceptions affecting their adoption. A critical evaluation of their effectiveness in developing climate-resilient and nutritionally enriched crops is presented. The findings suggest that integrating both approaches can maximize agricultural productivity and sustainability.
