Introduction to Plant Mutation Breeding: Different Approaches and Mutagenic Agents

Abstract

Purpose: Plant breeding plays a significantly important role in ensuring global food security. Among several methods of plant breeding, mutation breeding has shown remarkable success in crop improvement at a much faster rate than traditional breeding. The present study was carried out to review the different approaches and mutagenic agents of plant mutation breeding. Research Method: The review focused on both conventional and novel techniques of mutation breeding. To prepare a comprehensive article, the author reviewed selected available published information on experimental mutagenesis running back to the 20th century. Findings: In nature, mutations happen at a much slower rate hindering the scientists’ efforts of crop improvement. On the contrary, mutagens have provided the solution to a slow mutation rate by inducing mutations at much faster rates. Recent advances in science have opened up new paths of mutation breeding approaches. These approaches accompanied by state-of-the-art biotechnology has provided more effective, efficient, and robust results. For further development of mutation breeding, certain rules and regulations enacted worldwide must be addressed once more. Originality/Value: The study provides a comprehensive review on current knowledge of different mutation breeding approaches and mutagenic agents.
