Recommended Lists protocols
The AHDB Recommended Lists for cereals and oilseeds 2016–2021 (RL) project provides independent information about the performance of varieties. The RL publication is based on the analysis of hundreds of UK trials conducted across several years. The documents on these pages explain how the RL project is managed. They cover information on the trials and the decision-making process, including the reasons for adding and removing varieties from RL.
