Molecular markers are specific sequences of DNA that are used to identify and track traits in plants or other organisms. These markers are valuable tools in agricultural biotechnology because they allow researchers and breeders to associate particular genetic sequences with desirable traits such as disease resistance, drought tolerance, or yield potential. By utilizing these markers, scientists can more accurately select plants that possess the genetic characteristics needed to enhance breeding programs, making the selection process more efficient than traditional methods based on phenotypic observation alone.

In this context, DNA sequences provide a molecular fingerprint that can be used in various applications, including mapping genomes, conducting genetic diversity studies, and implementing marker-assisted selection in breeding efforts. Molecular markers play a crucial role in advancing our understanding of plant genetics and improving crop varieties for agricultural practices.
