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.
全基因组关联研究（GWAS）是用于挖掘与有用农艺性状相关的基因组位点的遗传工具之一。这项研究使我们能够找到与谷物产量和品质相关的新遗传标记。所研究的样本包括上世纪不同十年培育的春小麦品种。在普希金的VIR实验站对一组186份材料进行了为期3年的田间试验评估。总共发现了24个与六个生产力特征相关的单核苷酸多态性（SNP）。除了检测田间研究每年的显著标记外，还进行了荟萃分析。在4A、5A、6A、6B和7B染色体上检测到了与有用的产量相关农艺性状相关的位点。除了先前描述的区域外，在研究过程中还鉴定出了与谷物产量和品质相关的新位点。我们推测，利用起源于不同育种时期的对照品种使我们能够鉴定出与有用农艺性状相关的新标记。
