P9978
P9978 Maize Grain Hybrid
Very productive. Very stable. Very defensive.
P9978 is a modern erect-leaf hybrid with strong standability, drought tolerance and great all-round agronomic and leaf disease resistance package.
- Trials show that P9978 delivers industry leading grain yields in this maturity.
- Harvest moisture is at the mid-point between P0021 and P0362.
- Consider in place of P9721, P0021 or P0362 depending on maturity requirements.
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.
