The soybean aphid has become one of the most devastating pests to soybean in North America since its invasion in 2000. Soybean breeders have been seeking resistance sources and incorporating them into elite cultivars ever since 2000. As technology keeps updating over time, the process of mapping the aphid resistance QTL and facilitating it into the breeding scheme has become faster and easier. The results of mapping and fine mapping soybean aphid resistance gene in PI567537 will be presented. Based on fine mapping results, marker-assisted selection (MAS) system was well established, making the breeding scheme much more efficient than ever before. The MAS system will be discussed as well. We will also discuss how the resistance source screening system and new technologies were incorporated (52K SNP Chip and next generation sequencing).
