Oklahoma State Opens Advanced Turfgrass Research Center to Improve American Lawns and Golf Courses

New Facility Honors Pioneer While Advancing Grass Science

Oklahoma State University dedicated the Lionel K. Bentley Turfgrass Center in June 2026, marking a new chapter in the university’s five-decade commitment to grass research. The facility continues Oklahoma State’s 50-year legacy of turfgrass research. It also honors Lionel K. Bentley, a 1970 OSU graduate and pioneer in grass research. Located at the Oklahoma State Botanical Gardens in Stillwater, the 100-acre site hosts hundreds of experimental grass plots that contribute to America’s $40 billion annual turfgrass industry.

Researchers at the center work on developing improved grass varieties that address critical challenges facing homeowners, golf courses, and sports facilities across the United States. The team focuses on breeding grasses that can withstand extreme weather conditions, require less water, and resist common diseases and pests. These efforts directly support sustainable landscaping practices while maintaining the aesthetic and functional qualities Americans expect from their lawns and recreational spaces.

The research team examines multiple grass species, including Bermuda, Fescue, Buffalo, Zoysia, and Blue varieties. Each of these has distinct characteristics and growing seasons suited to different environmental conditions. Walk through the experimental plots, and you encounter scientists dedicated to specific breeding objectives that address real-world problems affecting grass performance throughout Oklahoma and beyond.

Cold-Tolerant Bermuda Grass for Golf Courses

Dr. Yanqui Wu leads efforts to develop cold-hardy Bermuda grass varieties suitable for use on local putting greens. Traditional Bermuda grass thrives in warm weather but struggles during Oklahoma’s unpredictable winter temperatures. His breeding program selects seeds with enhanced cold tolerance, allowing golf courses to maintain green playing surfaces longer into the fall and earlier in spring. This research addresses a significant challenge for course managers who currently face expensive overseeding programs or dormant brown fairways during cooler months.

The breeding process involves careful selection across multiple generations of grass plants. Researchers expose candidate varieties to controlled cold stress and monitor survival rates, recovery speed, and overall turf quality. Only varieties that demonstrate consistent superior performance advance to the next testing phase, which can span several years before commercial release.

Drought-Resistant Varieties Combat Water Scarcity

Dr. Mingying Xiang focuses her work on developing grass varieties that require minimal watering. When asked about her research objectives, she confirms the work centers on water conservation. Summer represents the most critical testing period, when Oklahoma’s heat and sporadic rainfall reveal which experimental grasses can maintain healthy growth with limited irrigation. This research carries particular importance as water restrictions become more common in municipalities across the American Southwest.

The drought-tolerance breeding program evaluates grass performance under precisely controlled water stress. Researchers measure root depth, leaf thickness, metabolic adjustments, and recovery rates after extended dry periods. Varieties that maintain acceptable appearance and functionality with 25-40% less water than standard cultivars represent potential commercial releases that could save billions of gallons annually.

Disease Resistance Research Protects Golf Course Investments

Researchers Kelli Black and Andrea Connally tackle the persistent problem of Dollar Spot, a fungal disease that plagues golf courses throughout the region. Connally explains the relationship between nitrogen levels and disease outbreak. Understanding the relationship between fertilization practices and disease outbreaks is key. It enables the development of management strategies that reduce chemical treatments and maintain pristine playing surfaces.

“If you don’t have enough nitrogen, we’ll see a lot of dollar spot,” Connally said.

The disease research program extends beyond Dollar Spot to include various fungal and bacterial threats that damage turf quality. Scientists screen grass varieties for natural resistance mechanisms, identifying genetic traits that provide protection without requiring intensive fungicide applications. This approach supports environmental stewardship while reducing maintenance costs for property managers.

Rigorous Selection Process Ensures Commercial Viability

Dr. Dennis Martin oversees the center’s breeding programs and explains the stringent evaluation process that determines which varieties reach consumers. The vast experimental field contains hundreds of small plots, each representing a different genetic line under evaluation. Few varieties complete the journey from initial breeding to commercial availability. The selection criteria are comprehensive, examining growth patterns, stress tolerance, and maintenance requirements. They also consider disease resistance and aesthetic qualities, all assessed over multiple years of field testing.

Dr. Shuhao Yu and other researchers dedicate significant time to observing grass plots. They look for subtle differences in growth habits, color retention, and recovery from damage. These detailed observations, combined with quantitative measurements of root development, water use efficiency, and nutrient requirements, create comprehensive performance profiles for each candidate variety.

Ongoing Battle Against Evolving Threats

Dr. Martin acknowledges the continuous nature of turfgrass improvement. Insects, diseases, and extreme weather conditions constantly evolve, requiring researchers to maintain aggressive breeding programs that stay ahead of emerging threats. He describes the research as an ongoing race where scientists gain temporary advantages through improved varieties, but pests and pathogens continue adapting. This reality ensures that turfgrass research remains a perpetual priority rather than a problem with a final solution.

The Lionel K. Bentley Turfgrass Center represents a substantial investment in agricultural science infrastructure that benefits multiple stakeholder groups. Homeowners gain access to grass varieties that require less maintenance and water while delivering superior appearance. Golf courses and sports facilities receive turf options that withstand heavy use and environmental stress. The broader turfgrass industry benefits from Oklahoma State’s commitment to fundamental research that drives innovation across the entire sector.

As summer progresses, researchers across the 100-acre facility monitor their experimental plots with careful attention. Each growing season provides fresh data about performance under real-world conditions. The knowledge generated at Oklahoma State University flows into commercial grass seed production, ultimately reaching millions of American lawns, parks, and athletic fields. The new research center ensures this vital work continues for decades to come, building on a half-century foundation of scientific excellence in grass breeding and turfgrass management.
