P8666 Maize Grain Hybrid

High performance hybrid with excellent agronomic properties.

A tall imposing plant with strong all-round agronomics, superior drought tolerance, Northern Leaf Blight resistance and staygreen.

  • Good husk cover, very good drydown and delivers top grain yields for maturity, with superior test weights.
  • Large-framed hybrid so established plant populations should be approximately 10,000 per hectare lower than planted for P8805.
  • Widely adapted from Dargaville to Ashburton where a hybrid of this maturity is required.

P8666 is intermediate in maturity between P8500 and P8805.

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.
