Research Project: Resilience of Grain Crops to Chilling and Waterlogging Stress

Location: Crop Production Systems Research

Project Number: 6066-22000-089-011-S
Project Type: Non-Assistance Cooperative Agreement

Start Date: May 1, 2023
End Date: Apr 30, 2028

1. Determine the degree of chilling tolerance of agronomically superior corn. 2. Quantifying the effects of waterlogging on emergence, physiology, and root traits. 3. Assess the biochemical response of stress-tolerant and sensitive corn.

Growth Chamber studies will be conducted using commercially grown high-yielding corn genotypes in the US midsouth region. Corn genotypes will be exposed to low vs optimum temperatures and waterlogging vs optimum moisture conditions to identify stress-resilient corn at germination, emergence, and early vegetative growth stages. Identifying stress-resilient corn at the vegetative stage offers an opportunity to overcome production challenges and efficiently utilize early summer rainfall for growth and development.
