Variety Positioning
•
•
Remains a leading Group 1 milling wheat and recognised for its high yield and the ability
to lay down protein efficiently. It has good grain characteristics and higher protein levels
than the other milling varieties. Crusoe is accepted by both domestic and export markets.
In areas of the West it is being grown simply for its resistance to disease with no intention
of going into a flour mill.
It is suitable for all regions of the UK except for Scotland. Performs consistently well across
all soil types although it can quickly lose tillers under stress conditions. Medium/fast in its
speed of development it is best drilled in the main drilling window and not ideal for either
early or late drilling. Average performance as a second wheat similar and slightly later to
ripen than other varieties in this category.
•
A moderate to high tillering capacity and semi-erect growth habit that is moderately
competitive against grass weeds. Short and relatively stiff straw with the very
characteristic ‘wax-less’ appearance. It has medium maturity.
•
Excellent disease resistance is especially strong against Yellow Rust, Mildew and Septoria
tritici which remains good and has been one of the key reasons for the varieties success. It
is very weak on Brown Rust and crop monitoring is essential. It is a good diversification
partner for Yellow Rust and the resistance is holding up well despite early observations of
seedling infection.
