Identification of Sweet Corn Hybrids Resistant to Root/Stalk Rot

For the past several years a "stalk rot" disease has been afflicting commercial sweet corn fields grown in the Willamette Valley. The disease seems to have a pathogenic basis, but the exact causal agent is unknown.
Eighteen hybrids with se or su endosperm were evaluated for resistance to root/crown rot. Ears were also evaluated for processing quality.

Objectives: Characterize su and se sweet corn hybrids for reaction to root/crown rot.
