Field Program – Yield Trials Approx yield trial plots in NC –Five NC locations (Sandhills, Plymouth, Lewiston, Caswell, Clayton) –Decent yields this year Additional 7500 plots coordinated from Raleigh –Five public cooperators (West, UT; Hawk, U Del; Murray/Mayfield, TAMU; Scully/Wilson/Tapp, Tifton; Blanco/Engstrom, Ames)

–Six private company cooperators (Syngenta; Pioneer; Dekalb; Mycogen; Pannar; Hogenmeyer) Field Program – Yield Trials

Germplasm in trials S 1 ’s of GEM Breeding crosses S 2 ’s of GEM Breeding crosses Advanced generation families/lines from GEM breeding crosses Breeding crosses per se Potential new germplasm for breeding crosses (CMLs, TZIs)

S 2 ’s of GEM breeding crosses Advanced generation families from GEM breeding crosses Breeding cross testcrosses Potential new germplasm for breeding crosses: Landraces from LAMP, CIMMYT prebreeding germplasm, HI inbreds Germplasm in future trials

2009 GEM-Raleigh releases Eleven recommended releases for 2009 from nine different breeding crosses Two new sources (CML420 and NS1)
