Soybean aphid [Aphis glycines Matsumura (Hemiptera: Aphididae)] is the most damaging insect pest of soybean [Glycine max (L.) Merr.] in the Upper Midwest of the United States and is primarily controlled by insecticides. Soybean aphid resistance (i.e., Rag genes) has been documented in some soybean accessions but more sources of resistance are needed. Incorporation of the resistance into marketed varieties has also been slow. Genome‐wide association mapping can aid in identifying resistant accessions by correlating phenotypic data with single nucleotide polymorphisms (SNPs) across a genome. Aphid population measures from 2366 soybean accessions were collected from published studies screening cultivated soybean (G. max) and wild soybean (Glycine soja Siebold & Zucc.) with aphids exhibiting Biotype 1, 2, or 3 characteristics. Genotypic data were obtained from the SoySNP50K high‐density genotyping array previously used to genotype the USDA Soybean Germplasm Collection. Significant associations between SNPs and soybean aphid counts were found on 18 of the 20 soybean chromosomes. Significant SNPs were found on chromosomes 7, 8, 13, and 16 with known Rag genes. SNPs were also significant on chromosomes 1, 2, 4 to 6, 9 to 12, 14, and 17 to 20 where Rag genes have not yet been mapped, suggesting that many Rag genes remain to be discovered. These SNPs can be used to determine accessions that are likely to have novel aphid resistance traits of value for breeding programs.

宿主植物对大豆蚜虫抗性的全基因组关联图谱。

大豆蚜虫[ Aphis glycines Matsumura（Hemiptera：Aphididae）]是美国中西部上半部最具破坏力的大豆害虫[ Glycine max（L.）Merr。]，主要由杀虫剂控制。大豆蚜虫对大豆蚜虫的抗性（即Rag基因）已有文献报道，但需要更多的抗性来源。将抗性掺入市售品种中的​​进展也很缓慢。全基因组关联映射可通过将表型数据与整个基因组中的单核苷酸多态性（SNP）相关联来帮助鉴定抗性材料。从筛选的栽培大豆（G. max。）和具有表现出生物型1、2或3特征的蚜虫的野生大豆（Glycine soja Siebold＆Zucc。）。基因型数据是从以前用于USDA大豆种质收集基因分型的SoySNP50K高密度基因分型阵列中获得的。在20条大豆染色体中的18条中发现了SNP与大豆蚜虫计数之间的显着关联。在已知Rag基因的7号，8号，13号和16号染色体上发现了重要的SNP 。SNPs在尚未定位Rag基因的1、2、4至6、9至12、14和17至20号染色体上也很重要，这表明许多Rag基因仍有待发现。这些SNP可用于确定可能具有新的蚜虫抗性性状的育种，对育种程序具有价值。
