NC7 and VA93B both had reduced disease incidence at the recommended rate of one pint per acre. Rovral did not reduce the level of disease. The yields in all other varieties were unaffected by Omega 500. Extremely wet conditions appeared to reduce the activity of Omega 500, an observation consistent with previous experience. NC7 and VA93B. Low yields in the runner lines may be due, in part, to rain delayed planting.
Runners show promise as lines for fields with severe Sclerotinia blight infestations.
Adoption of runners in North Carolina will depend on finding cultivars well-adapted to the state. Additional studies are focusing on CBR resistance and possible frost resistance in these lines. Entomology This research has confirmed that resistance to attack from the southern corn rootworm is available in several of the entries under development by the NCSU Breeding program. In most cases, much of the germplasm that has demonstrated resistance has NC 343 as a parent. This is the same parent as NC-6, which was released many years ago.
