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

star 1 star 2 star 3 = very highly significant yield advantage to Pioneer

star 1 star 2 = highly significant yield advantage to Pioneer

star 1 = 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.
