Turfgrass Seed Variety Evaluation Process

There is an urgent need to update existing Minnesota Department of Transportation (MnDOT) turfgrass recommendation lists and also to develop a fair process for keeping lists updated with data-driven recommendations. The goal is to re-evaluate the list of MnDOT approved turfgrass varieties and determine if there are varieties that need to be removed due to underperformance in recent field trials and also to determine if additional varieties should be considered for inclusion on the approved varieties list. This project will also address the procedure to be used to approve future turf grass varieties to be considered for inclusion on the approved turf grass varieties list. If current lists are not updated, and a process isn't developed, MnDOT seed mixes will once again revert to being of low quality, thereby reducing roadside turfgrass establishment success on projects.
