Variety performance review
Pioneer Full-Season Corn (P1197AM family) in the Mid-Atlantic South.
- Good
- Corteva Agriscience (Pioneer)
- 111–115 RM
- GMO
Trait package: Roundup Ready 2, Optimum AcreMax XTreme
Regional strengths
Full-RM hybrids fit the long Mid-Atlantic South season; gray leaf spot tolerance is increasingly important here as humidity supports persistent disease pressure. Pioneer maintains an active hybrid lineup tested in Virginia Tech and Maryland extension trials.
Regional weaknesses
Southern rust pressure can be severe in wet years on the Coastal Plain — verify the specific hybrid's southern rust rating before planting in eastern Maryland, Delaware, or eastern Virginia. Sandy Coastal Plain soils require higher seeding rates and irrigation to express full-RM yield potential.
