P9978
P9978 Maize Grain Hybrid
Defensive. Stable. Productive.
P9978 is a modern erect-leaf hybrid with strong standability, drought tolerance and a great all-round agronomic offering, including strong Northern Leaf Blight resistance.
- Trials show that P9978 produces industry leading yields in this maturity.
- Delivers in challenging through to high yielding environments and will reward the time taken to plant the best seeding rate for the growing situation.
- When planting early or into cold wet soils, switch to P9650, P0021 or P0200.
Widely adapted to all North Island growing regions where this maturity is required.

Scientific Designation
= very highly significant yield advantage to Pioneer
= highly significant yield advantage to Pioneer
= significant yield advantage to Pioneer
NS = not significant
CA = commercially acceptable
1 Positive HM differences means the bolded hybrid was drier at harvest, negative HM differences mean it was wetter.
2 A positive yield advantage means the bolded hybrid produced more yield, a negative yield advantage means it produced less.
