North Carolina GEM Project 2012

The North Carolina GEM Project conducted extensive yield trials in 2012, expanding to approximately 9,300 plots across five locations, including Clayton, Kinston, Lewiston, and Salisbury. Despite a rise from 6,000 plots in 2011, the results were mixed due to challenges like drought and heat stress. The project involved 5300 additional plots managed from Raleigh and collaborations with multiple public and private co-operators. Notably, new breeding crosses and germplasm from GEM breeding techniques were developed, enhancing allelic diversity and breeding potential. ###
