Presentation Transcript

  1. 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)

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

  3. 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)

  4. 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 prebreedinggermplasm, HI inbreds

  5. 2009 GEM-Raleigh releases • Eleven recommended releases for 2009 from nine different breeding crosses • Two new sources (CML420 and NS1)
