Advancements in wheat breeding and genomics presently explores the genomic interventions driving focusing on quantitative trait loci (QTL) mapping, marker-assisted selection (MAS) and genomic selection (GS). QTL mapping emerges as a pivotal method for pinpointing markers linked with desirable traits, facilitating MAS. Furthermore, genomic selection (GS) holds immense potential for crop improvement. It also delves into the current landscape of MAS and explores various prospects of GS for wheat biofortification. Looking ahead, accelerated mapping studies combined with MAS and GS schemes are poised to further enhance wheat breeding efficiency. Dense molecular maps and a large set of ESTs (Expressed Sequence Tags) have enabled genome-wide identification of gene-rich and gene-poor regions, as well as QTL, including eQTL (Expression quantitative trait loci). Additionally, markers associated with major economic traits have facilitated MAS programs in some countries and enabled map-based cloning of several genes/QTL. Resources for functional genomics, such as TILLING and RNA interference (RNAi), alongside emerging approaches like epigenetics and association mapping, are further enriching wheat genomics research. In this review, we initially present cutting-edge genome-editing technologies in crop plants, with a specific focus on wheat, addressing both functional genomics and genetic enhancement. We subsequently delineate the utilization of additional technologies, including GWAS, high-throughput genotyping and phenotyping, speed breeding, and synthetic biology, within the context of wheat breeding. We assert that integrating genome editing with other molecular breeding strategies will significantly expedite the genetic enhancement of wheat, thus contributing to sustainable global production.
