Marker Assisted Selection: A Novel Approach for Crop Improvement

The process of marker-assisted selection, or marker-aided selection (MAS), selects a trait of interest indirectly by considering a marker linked to the trait (e.g., quality, productivity, disease resistance, and biotic stress tolerance) rather than the trait itself. This integration of marker data with traditional selection approaches has become a widely studied and recommended method for advancing breeding programs. This technique has been extensively researched and recommended for animal and plant breeding. Here, we combine marker data with conventional selection to choose the best candidate for a future breeding program. Nowadays, the majority of MAS investigations employ DNA-based markers such as microsatellites, single nucleotide polymorphisms (SNPs), random amplification of polymorphic DNA (RAPD), amplified fragment length polymorphism (AFLP), and restriction fragment length polymorphism (RFLP). In this case, we discussed several kinds, techniques, and other features of marker Assisted Selection.
