Molecular Markers: Their Importance, Types, and Applications in Modern Agriculture

Abstract

: To meet the expanding global population's need for food, high-yielding hybrids, varieties, and superior populations of food crops must be developed. This can be accomplished by employing a molecular marker system. Breeders can use molecular markers to choose genotypes directly because they are not affected by the environment. Crop yields must be increased to meet the needs of growing people around the world, as well as the threat of new viruses, if climate change is to be avoided in the next decades. Agriculture is confronted with rising demand from a growing population, as well as dangers of restricted production area as a result of climate change, such as water scarcity, soil salinity, or harvest weather that is unpredictable. Plant breeding's ultimate goal is to create better crops. Crop productivity is something that can be improved. Any region (locus) in an organism's genome where the DNA base sequence differs among different individuals in a population is referred to as a molecular marker. DNA markers have been created in recent years and have shown to be effective tools for cereal breeding. The overall goal of this review paper is to evaluate the role, kind, and utility of markers in in crop improvement program.
