Field Program – Yield Trials

• Approx. 4500 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

• S1’s of GEM Breeding crosses• S2’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)

• S2’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)
