Recommended List 2023
National List (NL). It is a legal requirement that a variety is added to the NL before it can be sold. NL trials are used to determine whether a variety has value for cultivation and use (VCU), and is distinct, uniform and stable (DUS). BSPB run a three year series for this data to be obtained but in their third year of NL testing the varieties are also included in the RL trials.
'Where a variety has lower yield than the control varieties on the list it may still be listed for a specific use. In the 2023 RL there are four such varieties, one for use where the aggressive APYR strain of rhizomania occurs, two are ALS herbicide tolerant varieties and one has partial tolerance to Beet Mild Yellowing Virus.
The RL now carries out some trials that are not treated with foliar fungicides and the data (including yields) from of these 'untreated trials' can be found under the Disease section below. Please note that these results are from a limited number of trials (2 in 2019 and 3 each in 2020 and 2021).
Dates of release of data and years when trials carried out can be confusing – the table below gives examples of data collection from 2019 to 2023. Click on the RL List below to see the relevant data table.

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.
