“…Through GWAS, new genetic markers associated with grain yield and quality can be identified, and the association of previously detected loci can be confirmed. GWAS is widely applied in crop investigations to study genetic features related to important agronomic characteristics in plants [ 9 , 10 , 11 ]. The results of such a study can be used for the rapid breeding and development of new cultivars with desirable traits.…”

Genome-wide association studies (GWAS) are among the genetic tools for the mining of genomic loci associated with useful agronomic traits. The study enabled us to find new genetic markers associated with grain yield as well as quality. The sample under study consisted of spring wheat cultivars developed in different decades of the last century. A panel of 186 accessions was evaluated at VIR’s experiment station in Pushkin across a 3-year period of field trials. In total, 24 SNPs associated with six productivity characteristics were revealed. Along with detecting significant markers for each year of the field study, meta-analyses were conducted. Loci associated with useful yield-related agronomic characteristics were detected on chromosomes 4A, 5A, 6A, 6B, and 7B. In addition to previously described regions, novel loci associated with grain yield and quality were identified during the study. We presume that the utilization of contrast cultivars which originated in different breeding periods allowed us to identify new markers associated with useful agronomic characteristics.

Preserving and utilizing genetic diversity is crucial in crop breeding to address unpredictable situations such as climate change and evolving consumer demands. It serves as a source of new traits and alleles. Core collections are established from approximately 10-20% of conserved resources, and they are not only used for efficient management of genetic resources in seed banks but also applied in crop improvement programs and new gene discovery. These core collections demonstrate diversity based on the geographic origin of genetic resources and provide information on genetic similarity among resource types and collection regions. Recent advances in high-throughput genotyping has enabled high-resolution association mapping, allowing for the precise discovery of new genes and QTLs. The wheat genetic diversity and population structure of core collections are important in determining appropriate GWAS statistical methods for detecting these novel genes and QTLs. To maximize their utility, collecting detailed phenotypic data is crucial. This will expand their application in gene discovery, marker development, and more. In this study, we provided reviews for wheat core collection in the world to face the digital breeding era, where precise gene detection and manipulation are possible. The accumulation of genetic diversity, and phenotypic and genotypic information by core collections will contribute to breeding cycle acceleration and trait selection optimization.
