P1477W Maize Silage Hybrid

A balanced all round full maturity hybrid.

A white-grained hybrid producing, attractive wellfilled cobs for high starch content silage for maximum milk production.

  • Tall, erect leaf, modern plant type with excellent roots, stalks, drought tolerance and staygreen.
  • Superior Northern Leaf Blight, Common Rust and Eyespot resistances for season long leaf health.
  • A great option where leaf diseases, lodging or yield stability are considerations.

An outstanding companion for P1636.

Plant before 20th October into high yielding paddocks in all northern growing regions.

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 DM differences means the bolded hybrid was drier at harvest, negative DM 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.
