Hybrid Descriptions<br />
PR39G12<br />
» Intermediate Maturity » Maturity Class 5<br />
» Primary End Use: Forage<br />
PR39G12 is an impressive, very large stature, later maturing and very high yielding hybrid. PR39G12 is a popular choice of<br />
growers who wish to exploit their warm favourable maize fields by maturing a high yielding crop of high starch content silage.<br />
Hybrid Characteristics<br />
• Single cross<br />
• Tall, large stature hybrid<br />
Grown In The Open<br />
• Adapted to light to medium soils<br />
in southern areas of England<br />
and also warmer sites in the<br />
Midlands and East Anglia<br />
Grown Using The Samco System<br />
• PR39G12 is not normally grown<br />
under film<br />

PR39T83<br />
» Late Maturity » Maturity Class 4<br />
» Primary End Use: Forage<br />
PR39T83 is only suitable for planting under the Samco System in the UK and Ireland. In both trials and commercial use<br />
it has produced very high forage dry matter yields of good starch content. It has a tendency to double cob when grown<br />
under film and this is partly responsible for its high silage dry matter and starch yields when grown using the Samco<br />
System. PR39T83 has shown good resistance to eyespot (Aureobasidium zeae).<br />
Hybrid Characteristics<br />
• Single cross with flint grain<br />
• High grain yields<br />
Grown In The Open<br />
• Not normally grown in the<br />
open<br />
Grown Using The Samco System<br />
• For silage production in the UK<br />
and Ireland except in the most<br />
unfavourable sites in northern<br />
counties<br />
