Profile

New for 2021 is Crossfit CR – a variety with outstanding qualities. Crossfit stands out from other varieties as it is resistant to clubroot which is on the increase in the UK.

It is a quad layered variety - meaning it has resistance to clubroot, TuYV Protection, Pod shatter resistance as well as RLM7 stem canker resistance. No other variety in the UK has all of the above stacked traits together making it the ideal variety for a worry free crop in a clubroot situation.

Crossfit CR has been in trials in the UK for 5 years. Not only is it recommended for use on clubroot infected land it has be seen to produce high yields - 107 % - and has a very high oil content - 46.8%. Crossfit is slightly later flowering than some varieties. It has an maturity score of a 6, with a stiff stem scoring 8’s for both lodging and stem stiffness.

Alongside clubroot resistant varieties it is also important to consider other factors such as the PH of the soil should PH 7 or above, and calcium can be added, lengthening rotations, and consideration can be given to the eradication of brassica weeds, such as runch and charlock which can amplify the problem.

Crossfit CR may, however, be infected by certain strains and infections that have been reported in some fields.
