É«»¢ÊÓƵ of Missouri (LU) researcher Suman Veeramasu is leading a project to identify peanut cultivars — varieties selected for specific traits — capable of thriving under Southeast Missouri’s growing conditions.

Each cultivar offers different characteristics, such as earlier maturity or greater tolerance to heat and drought, which can affect its performance across the state. Through field trials near Sikeston, the research team is evaluating cultivars for yield, early maturity, oil quality and tolerance to drought, temperature changes, pests and diseases.

The project aims to provide Missouri farmers with locally relevant cultivar recommendations and production guidance. Farmer feedback plays an important role in shaping the project’s priorities.

“Farmers care about yield, of course, but yield alone does not determine whether a cultivar will succeed in Southeast Missouri,” Veeramasu said. “They raised concerns about planting conditions, stand establishment, maturity, harvest timing, pest and disease pressure, weather variability and market requirements.”

Researchers also hope to establish a long-term peanut breeding and production program suited to Missouri’s growing conditions, keeping in mind how cultivars can perform differently across the state.

“We have learned how much the start and end of the growing season matter,” Veeramasu said. “Missouri summers are great for peanuts, but the challenges come at either end.”

Cool spring soils can slow germination and plant establishment, while falling temperatures can limit pod development later in the season. Researchers are studying whether early-maturing cultivars can complete their life cycles within Missouri’s warm-weather window and help farmers reduce risks associated with spring cold and fall frost.

“I do not view traits independently,” Veeramasu said. “The ideal Missouri peanut would combine rapid establishment, early maturity, competitive yield, tolerance to environmental stresses and pests and high-oleic seed quality.”

High-oleic seeds contain high levels of oleic acid, which can extend the shelf life of peanuts and increase the crop’s market value. Combining high-oleic seed quality with competitive yields and regional adaptability could offer Missouri farmers both production and marketing advantages.

The first-year trials remain underway, and researchers continue collecting and analyzing data. Although the team has observed clear differences in how cultivars respond to Missouri conditions, researchers plan to complete further analyses before drawing conclusions about individual varieties. The trials have reached the expected pod-maturation stage, with preliminary results anticipated by the end of the year.

Beyond cultivar selection, the project could provide Missouri-specific information to guide farmers’ planting and production decisions while supporting communities across the state. Expanded peanut production may strengthen relationships between LU and farmers, create new agricultural opportunities and contribute to a more resilient local economy. Continued study will help determine whether peanuts can become a practical long-term option for the region.

“Expanding peanut production in Missouri will require close cooperation among researchers, Extension specialists, farmers, industry, buyers and equipment providers,” Veeramasu said. “É«»¢ÊÓƵ can play an important role by building the research and Extension foundation needed to support those decisions and help growers adopt peanuts with greater confidence.”
