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).
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 each in 2018 and 2019).
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 section below) for 2020 (limited data) and 2021 RLs.
Revised recommended list
The following tables are those for the 2021 Recommended List but updated with the 2020 results (the three years of data used in these are 2018, 2019 and 2020). This data has been released early to provide growers with the latest information before they sow their 2021 crop. The 2022 RL table with the new varieties for commercial sowing in 2022 will be available for release in April.

* For 2021 seed ordering growers should use this table, which gives variety ranking based on the new calculation of adjusted tonnes. This change in calculation results in some small differences in ranking of varieties. In general, most varieties ‘adversely’ affected do not have quite the same premium from high sugar concentrations as previously. The new adjusted tonne is basically the same as sugar yield but in this table rounding of data has caused some small differences in a few cases.

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.
