Crusoe is a restored hybrid Recommended List variety for growing on land infected with common strains of clubroot. It has a high gross output, high resistance to stem canker, good resistance to light leaf spot with good stem stiffness and resistance to lodging. It is TuYV resistant.
Crusoe is the latest of the highly successful NPZ UK clubroot breeding programme taking yields to nearly 10% higher than former stalwart variety Crome in the E/W region.
Phoma resistance has always been the Achillies heal of the clubroot varieties. However Crusoe sees a huge leap forwards in it's rating against phoma to bring it inline with leading hybrids.
Benefiting from TuYV resistance too Cruscoe provides an unrivaled offer in the clubroot market.
Clubroot tolerant oilseed rape varieties are capable of tolerating the more common strains of the clubroot pathogen but new strains are evolving constantly so complete resistance is not possible. Good agronomic practice such as longer cropping rotations, maintaining soils at pH7, delaying drilling and reducing the prevalence of hosts such as brassica based cover crops as well as using a clubroot tolerant oilseed rape variety will all help to reduce the damaging effects of this disease.
