P8666
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
= 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.
