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)
Field Program – Yield Trials
– Six private company cooperators (Syngenta;
Pioneer; Dekalb; Mycogen; Pannar;
Hogenmeyer)
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)
Germplasm in future trials
• 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
2009 GEM-Raleigh releases
• Eleven recommended releases for
2009 from nine different breeding
crosses
• Two new sources (CML420 and NS1)
