Technical Abstract: Evaluation and rating plots were planted at the Saginaw Valley Research & Extension Center (SVREC) in Frankenmuth, MI in 2016 that focused on Cercospora leaf spot (CLS) and Rhizoctonia crown and root rot (CRR) disease performance of a wide range of Beta vulgaris materials. CLS and CRR trials were conducted in conjunction with the Beet Sugar Development Foundation (BSDF) and CLS trials included USDA-ARS cooperator germplasm as well as germplasm screening for the National Plant Germplasm System. All trials were planted following normal fall and spring tillage operations The CRR Eastern Evaluation Nursery had 298 entries from four companies. The nursery was inoculated with a dry ground barley inoculum of Rhizoctonia solani, anastomosis group 2-2 (highly virulent isolate). Roots were dug and each root was rated for disease severity. Variety disease index means for the entire nursery ranged from 4.8 to 6.8 (mean = 5.9). The CLS evaluation nursery had 204 entries from three companies and was inoculated with a liquid spore suspension of Cercospora beticola. 224 USDA-ARS breeding lines from four USDA cooperators.
