The uses of traditional methods and instruments have led to a great success in plant breeding through the creation of better cultivars.Currently, the accessibility of genomic data as well as techniques is fueling a novel paradigm in the breeding of plants since they make it easier to explore the relationship between the genotype and phenotype, solely for intricate traits.The mass sequencing of genomes, transcriptomes, is producing a multitude of genetic data and metabolomics made feasible by Next Generation Sequencing (NGS) technology.The analysis of NGS data utilizing advances in bioinformatics makes large sets of molecular markers available, fosters the discovery of new genes and regulatory sequences, and even provides accessibility to huge number of molecular markers.Breeders are able to comprehend molecular underpinnings of many complicated phenotypes, all as a result of genome-wide expression research.A complicated characteristic, drought tolerance (DT) is now a major danger to the world's food security since it limits productivity.Developing drought-tolerant wheat cultivars through traditional breeding has been hampered by itscomplexity.Hence, to increase wheat's resistance to drought, marker assisted selection (MAS) and genetic engineering have been employed to change some genes or transcription factors.With the evolution of new concept, "Omics," it has become easier for identification and characterization of genes related associated to drought tolerance.To recapitulate, breakthrough in genomics is giving breeders innovative tools and technologies, which enable a giant step ahead towards the advancement in plant breeding by developing drought tolerant wheat cultivars.
