Zoysiagrass Cultivars to Consider in Kansas

Options for sod producers, golf courses, and lawns

K-State has been closely involved with Texas A&M University on release of zoysiagrass cultivars over many years.  Sod producers in Kansas can consider these cultivars for grow-in and release to the industry.

Vegetative Zoysiagrass

Meyer Zoysia

Meyer (Z. japonica) is the cultivar that has been widely used in Kansas and was released in 1951 from the USDA, Beltsville, MD, and the USGA, Far Hills, NJ. It has been widely used over many areas since it was released in the 1950s.  Breeding efforts have been continuing to develop cultivars that are well suited for the Midwest – more below.

Innovation Zoysia

K-State has worked closely with Texas A&M since 2004 in development and release of new zoysiagrass cultivars that have good cold tolerance.Innovation was released from Texas A&M and K-State in 2015, and is the first zoysiagrass for our region that has a fine texture, high quality, and cold tolerance equivalent to Meyer. It was a breeding release that involved a cross between Z. japonica and Z. matrella. Z. japonica has the cold tolerance and Z. matrella has fine leaf texture. This is a unique cultivar with a finer texture than Meyer but also has cold tolerance. It is presently provided by Sod Solutions to sod producers.

Chisholm Zoysia

Chisholm (Z. japonica) was released in 2012 from Texas A&M and K-State. It has a coarser leaf texture, but is deep-rooted, has good drought tolerance, and would perform well in southern Kansas. More details here

DALZ 1701 Zoysia – Vegetative

In 2022, after 10 years of research evaluation across multiple states in the transition zone, a new zoysiagrass cultivar (experimental name DALZ 1701) was released by Texas A&M, K-State, and Purdue.  A standard cultivar name for this will soon be available; it will likely be provided by sod producers in the next couple of years.  Highlights of DALZ 1701: • Freezing tolerance of DALZ 1701 is similar to Meyer and Innovation • Exhibits superior heat tolerance than Meyer and has performed well in Dallas, TX • Drought tolerance is better than Meyer  • Has dark green genetic color and better fall color retention than Meyer • Exhibits superior tolerance to large patch, take-all patch, mites and hunting billbugs than Meyer.

Seeded Zoysiagrass

Zenith Zoysia – Seeded

Zenith (Z. japonica) is a seeded cultivar that was released in 1993 and has performed well in Kansas and is available through purchase online. It has been well established on several golf courses in the state and has performed very well. More details here

Two-Minute Turf Extension Video: Aerification Impacts

Dani McFadden, Ph.D. student in Horticulture and Natural Resources, is conducting research on the impact aerification on zoysia thatch reduction and root development. This research is presented in greater detail in the

Research in progress: zoysia seedhead suppression

(Megan Kennelly, KSU Plant Pathology)

I was out looking at our zoysiagrass breeding plots the other day and in a couple of plots I saw some seedhead development:

 

This was unusual, as we typically see this in spring, and it’s probably just a unique physiology of these couple of breeding lines. Anyway, this observation prompted me to mention that we are continuing KSU’s work on zoysiagrass seedhead suppression. You may have seen the articles about the prior excellent work by Dr. Hoyle and colleagues which you can view here:

Suppressing Meyer zoysiagrass seedheads

and here (academic peer-reviewed version)

We are following up on this work with additional trials to hone in on the biology and management of seedheads, fine-tuning application timings of ethephon. Stay tuned for results in the coming 1-2 years as we collect data. The project team members are PhD student Manoj Chhetri, Jack Fry, Jared Hoyle, me, and Aaron Patton (Purdue). The project is funded by the GCSAA, Heart of America Golf Course Superintendents Association, and Kansas Turfgrass Foundation.
