Abstract

Genetic mapping and marker-assisted selection (MAS) have emerged as powerful tools for accelerating crop improvement efforts worldwide. Genetic mapping involves identifying and characterizing the location of genes or genetic markers on a chromosome, providing crucial insights into the genetic makeup of crops. MAS, on the other hand, utilizes genetic markers to facilitate the selection of desired traits in plants, enabling breeders to identify individuals with the desired genetic makeup more efficiently than traditional methods. This article provides an overview of genetic mapping and MAS, discussing their benefits, applications in crop improvement, and future directions. By harnessing the genetic diversity of crops and targeting breeding efforts with precision, genetic mapping and MAS offer tremendous potential for enhancing crop yields, resilience, and sustainability in the face of global challenges such as climate change and food security.
