Objective: Identify sweet corn hybrids with suitable processing quality that have high, stable yields and tolerance to root rot disease complex.
Objectives for 2011 and Accomplishments:
1. Examine the yield and disease levels of sweet corn plants grown from seeds treated with germicidal light.
2. Evaluate biological applications to sweet corn seed parents and subsequent Fusarium presence on silks and seed infection/contamination.
Root rot of sweet corn is an important disease of sweet corn in the Willamette Valley of Oregon, first diagnosed in the 1990's. Root rot is caused by a disease complex including Pythium arrhenomanes, Phoma terrestris, and Drechslera spp. Severe root rot was shown to reduce yield in Golden Jubilee by as much as 3 T/A and Super Sweet Jubilee by 1.5 T/A. Root rot also impacts crop quality by reducing ear fill and dimpling corn kernels.
