Texas Potato Breeding Report 2020 The Texas A&M AgriLife Research Department of Horticultural Sciences Texas A&M University Isabel Vales, Douglas Scheuring, and Jeff Koym College Station and Lubbock 2020 Springlake Harvest Due to travel restrictions by the University, we had to travel in separate vehicles, stay in separate rooms, and of course masks. COVID-19 added a significant cost to the Program for travel. Fortunately, we were able to plant and harvest our trials at both Springlake and Dalhart with the team staying healthy.
