Planting date/cultivar evaluation: Thirty-six sweet corn cultivars were evaluated for resistance to natural infection by common smut (Table 1). Plots were seeded to 30,800 plants/acre on May 16 and Jun 23 on the Hermiston Agricultural Research and Extension Center on Adkins fine sandy loam (pH 6.7, 0.9% organic matter). The...
Thirty-one sweet corn cultivars were evaluated for resistance to natural infection by common smut. To determine if there is High Plains virus resistance in commercial processing sweet corn cultivars, trials were conducted at the Hermiston Agricultural Research & Extension Center, and in two commercial sweet corn production fields near Moses...
Russet Burbank, Russet Norkotah, and Shepody tubers infected with Potato virus Y strains (PVYO, PVYN:O, PVYNTN) were tested from storage at 4A degrees C at the initiation of sprouting and then the same tubers were tested again from storage at 4A degrees C seventy eight days later. Samples were taken...
Nearly complete sequences of RNA-CP and 3'-proximal RNA-TGB were determined for 43 samples of potato mop-top virus (PMTV) originating from potato tubers and field soil from Sweden, Denmark and the USA. The results showed limited diversity and no strict geographical grouping, suggesting only a few original introductions of PMTV from...
