Final Project Results

Achieving the objectives
• Collaboration among USB, QSSBs and regional checkoff programs resulted in the completion of field analysis and genotyping of the 5,600 NAM lines across multiple locations. Evaluation of this many lines in field trials are a huge undertaking, but are necessary for successful identification of key genes controlling yield and composition.
• A total of 5,303 unique SNP markers that were effective in identifying genetic differences among the 5,600 NAM lines were identified.
• Groups of genes (QTL) associated with yield were identified on 17 of the 20 soybean chromosomes
• A selection procedure for identifying ideal parents to produce maximum yield is being developed and tested.
