The North Carolina GEM Project conducted yield trials and evaluated germplasm in various locations across North Carolina. The project involved a large number of trial plots and focused on breeding crosses and potential new germplasm. Mixed results due to heat and drought stress were observed at some locations. The project also included a nursery for S1 and S2 development and the production of new breeding crosses. Cooperator companies included Dupont Pioneer, Monsanto, Dow Agrosciences, and more.

Germplasm in trials • S2 families derived from GEM breeding crosses • GEM released lines • GEM breeding crosses • Potential new germplasm for breeding crosses
Nursery • Approx. 3000 rows plus 1200 rows in isolation • Six GEM breeding crosses for S1 development • Six GEM S1’s for S2 development • Allelic Diversity (450 rows in summer, 120 in winter) • Forty-one new breeding crosses produced (24 GEM x GEM and 17 tropical x GEM) • GEM bulk increases for released lines and potential releases
