Variety Positioning
•
Agrii’s number one variety in Scotland and has increasingly taken market share as
Viscount and Horatio have declined in their acreage. Rated as ‘Medium’ for distilling, with
soft biscuit quality and also meets full uks for export so it is also grown in port catchment
areas. However in the key biscuit markets in the East and West the acreage is now
declining due to problems with disease resistance breakdown.
•
Suitable for all soil types including light land and performance appears reasonable as both
a first and second wheat although its parentage might suggest otherwise. A fast developer
so not suited for early drilling but best from mid-September through to mid-October.
•
Moderate to high tillering capacity with a moderately competitive semi-erect growth
habit that can be useful where grass weeds are a problem. Develops into a taller strawed
variety with moderate stem stiffness that responds well to PGR applications. Medium
maturity and as with most soft wheats give priority at harvest to mitigate against
sprouting. Orange Wheat Blossom Midge resistance is a real bonus.
•
Until recently it had excellent Yellow Rust resistance but this has recently broken down
and now has a relatively weak disease profile overall. It has Soil-borne Cereal Mosaic Virus
resistance and, although the incidence of this disease is low, it appears to be increasing
and may be useful on affected soils.
