Recommended List 2021
'Where a variety has lower yield than the control varieties on the list it may still be listed for a specific use. In the 2021 RL there were three such varieties, one for use where the aggressive APYR strain of rhizomania occurs and the other two are herbicide tolerant varieties.
Three of the 13 trials drilled each year are also used for National List (NL) purposes. It is a legal requirement that a variety is added to the NL before it can be sold and the trials are used to determine whether a new variety has value for cultivation and use (VCU) and is distinct, uniform and stable (DUS).
Dates of release of data and years when trials carried out can be confusing – the table below gives examples of data collection for the 2017 to 2021 RL tables (these are the tables from which growers select varieties for that season’s sowing). Click on the RL List below to see the relevant data table. In addition, the RL now carries out trials to determine the yield of varieties that have not been treated with foliar fungicides (see under Disease for 2020 (limited data) and 2021 RLs.

This updated version of the 2020 RL table is provided to allow growers to see how the varieties performed in 2019 trials. The official published 2020 RL table used data from 2016, 2017 and 2018 trials, this is an updated one using 2017, 2018 and 2019 trials data to allow growers to see how varieties are performing with the latest data. The values may appear lower in this new version but that is because of the change of control varieties, which have higher yields than those used in the official table. Also take care when looking at early sown bolting figures, some varieties that have bolting values close to the threshold can have their recommendation for early sowing changed by small fluctuations in bolting levels between seasons.
Definitions of susceptibility to pathogens
Susceptible – A variety that becomes infected by a pathogen and shows full symptoms of the disease; significant yield penalties may result.
Tolerant – A variety that is infected by a pathogen to the same extent as a susceptible variety, but expresses little or no symptoms.
Partially-resistant – A variety that is infected by a pathogen, but the pathogen is inhibited in its movement or multiplication.
Complete resistance (immunity) – A variety that is not affected by the pathogen at all.
Multiple resistance – Inclusion of more than one resistance genes to protect against different pests and/or diseases.
