Breeding for increased protein concentration, sudden death syndrome resistance, and soybean cyst nematode resistance in soybean
Soybean (Glycine max (L.) Merr.) is one of the most important agronomic crops in the USA and worldwide with dynamic uses in food, industry, and feed. Development of improved soybean cultivars is critical to provide the resources necessary for a growing world population. Approximately 83 million acres/33.5 million hectares of soybean were harvested in 2016 in the USA, and Illinois is one of the top soybean producing states. For the past several decades, soybean breeders have sought to protect and improve the economic value of soybean through genetic improvement of seed composition and disease resistance traits. In order for a gene to be effectively incorporated into a breeding program, it must maintain its desired effect across many genetic backgrounds without a negative effect on agronomic traits such as yield. The objective of this dissertation was to identify genetic regions that can be used in breeding programs to successfully increase protein concentration, sudden death syndrome (SDS) resistance, and soybean cyst nematode (SCN) resistance.
