Newsletter of Turfgrass Producers of Texas Summer 2018 generally’ grouped into these three categories based GENETIC RESEARCH mostly on leaf texture, but also on their shade tolerance and other traits. For example, coarse-textured zoysias have typically been thought of as Z. japonicas while SHINES LIGHT INTO fine-textured zoysias were consideredZ. matrellas or Z. pacificas. As a result, some zoysiagrass cultivars have been misclassified with many intermediate types ZOYSIA’S FAMILY TREE simply being called japonicas or matrellas. However, By Susana Milla-Lewis, PhD, & Jennifer A. Kimball, PhD recent genetic research is shedding light on the inter- Edited for “Rooted in Research” by Casey Reynolds, PhD connectedness of these species and the diversity in There are approximately 30 different species of traits they each produce. turfgrasses commonly found throughout the world, and each has its own set of characteristics that make Figure 1 it uniquely adapted for use. These adaptations can be Zoysiagrass species are cross-fertile and easily grounded in climate, rainfall, mowing height, stress interbreed with one another.

A few examples of this include Mascarenegrass (Zoysia pacifica, previously identified cultivars like Cavalier, Crowne, Zeon, and Zorro. as Zoysia tenuifolia). Historically speaking, zoysiagrass While these cultivars typically have finer texture than cultivars used for turfgrass have often been ‘very (Continued on Page 6) 40+ Years Experience in Sod Farm Irrigation Design 800.848.3959 Wyatt Bosse Needville, Texas 77461 [email protected] The Pallet 2 Summer 2018 Greetings from the new Texas Turfgrass Extension Specialist Howdy! Allow me to introduce myself. My name is Dr. Becky Grubbs, and I THE am the new Turfgrass Extension Specialist with Texas A&M AgriLife. PALLET A little about me… I grew up in the DFW area (Lewisville, TX), and my parents still reside in Produced by TURFGRASS that part of the state today. My first two PRODUCERS OF TEXAS degrees were completed at Texas Tech University in Lubbock, and then I went BRENT BATCHELOR on to pursue my PhD in Crop and Soil Executive Director Sciences at the University of Georgia P. O. Box 1571 Bay City, TX 77404-1571 in Athens, GA.

We want to offer more opportunities for you to gain knowledge and be around Putting a value on a story other turf producers. We are in the early stages of plan- Walk through the diamond district in Manhattan ning a fall equipment field day. and in the course of one block, at least a dozen men will stop you and ask if you’re hoping to sell a diamond ring. A few blocks away, Tiffany will happily sell you a diamond ring. Buy a $7,000 ring at Tiffany’s and walk over the one of these guys and you’ll be lucky to get $1,000 for your new ring. That $6,000 is what you paid for the story. It’s the cost of the box, the lighting, the salespeople, the architecture and most of all, the special feeling. Do a blind taste test. In one glass, wine from a $10 bottle. In the other, wine from a $200 bottle. The untasted difference between the two is what you paid for the story. The list goes on and on. Just about every- thing we buy comes with a story included. And yet, most creators, sellers and marketers don’t invest enough, don’t take enough care, and don’t persist enough in making sure the story is worth what you paid for it. As I ponder this statement from a turf marketing standpoint I am struck by the fact that our association does and needs to continue to tell our story and the sto- ry of natural turf produced on Texas farms that provides the best option for folks to enjoy the managed open spaces they encounter. That may be a home lawn, a golf course, a sports field, a park or any other area that turf is an option. SO, going forward think about our collec- tive turf story and how we tell it to our end users.
