Crocodile CR

Status: AHDB Candidate List 2019-2020

Crocodile CR had a fantastic second year in trials delivering yields that set a new benchmark for clubroot resistant varieties and performed extremely well alongside some of the best AHDB recommended material.

Not only has Crocodile CR closed the gap between clubroot resistant varieties and ‘normal’ varieties it is actually out-yielding them! With a high infestation of clubroot last year, it is becoming more apparent that the disease is moving south rather than just being a problem in Scotland and northern England.

Crocodile CR joined the candidate list this November and is the first variety to join the list on its own merit rather than having special clubroot resistance dispensation. It is one of the highest yielding varieties on the list setting new standards for clubroot resistant varieties going forward. It has a strong score for light leaf spot (6) and good standing power. At DSV we always aim to deliver yield with traits rather than traits at the expense of yield. The disease has become more apparent on farm during the last 5 years, with closer rotations, meaning it is often costly and hard to control.

Due to the rapid development of the lower branches of Crocodile CR DSV recommends a sowing rate of 40 – 50 seeds and a PGR in spring is only required on fertile sites to ensure efficient harvestability. Its vigorous autumn growth allows it to be drilled across a broad range of dates without any issues.


Crocodile CR is recommended for growing on land infected with common strains of clubroot. Crocodile CR may, however, be infected by some strains and infections that have been reported in some fields. It is important that growers protect the clubroot genetics by only planting the variety where clubroot is known to be an issue.
