Parentage: Hussar x Lynx
Key Benefits
Has found favour with UK farmers as a good 2nd wheat
A high tillering, vigorous variety that establishes well in tough
seedbed conditions
Agronomy
Napier has moderately short, stiff straw. It is particularly suited
to the second wheat slot. The graph below demonstrates feed wheat
performance. Varieties on or above the line perform consistently
as a 2nd wheat. Those below the line are less consistent as a 2nd
wheat.

Napier is resistant to the Brigadier race of yellow rust that affects
Savannah, and the Oxbow race which affects Robigus and Wizard. It
is in the same diversity group as Einstein and Access.
Napier is moderately susceptible to eyespot, so treatment with cyprodinil
at T1 is required in a risk situation e.g. 2nd wheat.
