Technical Abstract: Evaluation and rating plots were planted at the Saginaw Valley Research & Extension Center (SVREC) in Frankenmuth, MI in 2013 that focused on Cercospora leaf spot and Rhizoctonia seedling disease performance of a wide range of Beta vulgaris materials. Leaf spot trials were conducted in conjunction with Beet Sugar Development Foundation (BSDF) and included USDA-ARS cooperator germplasm. A total of 564 entries were evaluated using a disease index based on defoliation that ranged from 0 (healthy leaves) to 9 (no leaves). At our September 12 rating, means of the resistant and susceptible internal controls for the entire nursery were 3.1 and 5.2, respectively. Cercospora values 4.0 or less are promising. The Rhizoctonia seedling inoculated trial was done to evaluate the feasibility of conducting a seedling Rhizoctonia disease nursery and to gauge whether results would be useful. All 68 entries were indicate East Lansing germplasm enhancement materials, and stand establishment was generally good to excellent. Post-disease expression stand counts reflect loss to seedling disease, and were generally quite severe, with less than half of the pre-disease stand counts remaining, on average.
