The objective of this project is to improve soybeans for durable resistance to emerging populations of soybean cyst nematode and yield limiting fungal pathogens that are adapted to Tennessee. The researchers will use standard breeding techniques combined with DNAmarker assisted selection. Primarily known markers tagged to resistance genes are used to select desirable soybean progenies for nematode resistance. The researchers have identified unique parent material with broad resistance to SCN that may provide durable resistance and are transferring resistance genes from these unique sources into elite soybean cultivars.
