Outstanding light leaf spot resistance
- Consistently high yielding
- Excellent oil content
- Very stiff straw
-
Low glucosinolates
Tuscan is a very high yielding restored hybrid oilseed rape,
with high oil content and an excellent agronomic profile, including
outstanding resistance to light leaf spot. Tuscan has very high
UK performance but is particularly suited to the North.
It’s resistance to light leaf spot is one of the best
available and as a consequence, Tuscan is particularly suited
to the north of England and Scotland where light leaf spot is
of greater economic importance.
Light leaf spot is the key disease of oilseed rape in the north.
Responsible for yield losses in excess of 1.5 tonnes/ha in commercial
crops and increasingly difficult to control in the field, varietal
resistance is recognised as the effective and economical way
forward.
Tuscan has good stem canker resistance although this is of
less importance in northern regions.
Gross Output
Tuscan has a very high gross output when grown in the north.
Profitable oilseed rape requires both high yield potential and
high oil content, the combination of which produces the overall
gross output.
Tuscan offers both yield and oil content - and low glucosinolate
content.
Agronomic Characters
Tuscan is medium height with excellent straw characters, offering
both very stiff stems and a very high resistance to lodging. These
important characters ensure easy harvesting even under adverse conditions.
Flowering
Tuscan has both medium flowering and maturity. Avoiding the risk
of damage from late spring frosts, the pod fill period is maximised
without giving a late harvest.
Pods are large and fill evenly with large seed.
Sowing and establishment
Tuscan is a fully restored hybrid and, like other hybrid oilseed
rape, has high vigour, giving rapid emergence and good autumn growth.
Drilling
Suggested seed rate is 500,000 viable seeds per hectare to achieve
the optimum plant population under average conditions.
Fertilisers
Where soil reserves are low or high trash residues are 'locking
up' any nitrogen that is present, autumn applications of nitrogen
are advised where possible.
Sulphur
It is vital that nitrogen is available to the plant from the moment
it starts to grow after winter dormancy. Utilisation of high rates
of nitrogen are dependent on adequate availability of Sulphur. Insufficient
Sulphur will seriously restrict the potential for yield responses
from any nitrogen applied.
