Abstract
A vegetatively reproduced buffalograss cultivar, named 609 Buffalograss, is distinguished by its excellent overall turfgrass quality, rate of establishment, good cold tolerance, high density, and excellent color. This cultivar is adapted to low maintenance conditions and has the ability to maintain growth and color later into the fall than other warm season grasses.
Description
Buffalograss, Buchloe dactyloides (Nutt) Engelm., is a perennial, low growing, drought tolerant species native to the Central and Southern Great Plains that spreads by profusely branching stolons and thrives under semi-arid conditions with heavy to moderate grazing.
609 Buffalograss is distinguished from other commercially available cultivars in being a vegetatively propagated female plant with a darker green color than `Prairie` Buffalograss. 609 Buffalograss has better overall quality, appearance, density and uniformity than seeded varieties. It has a vigorous, low growing growth habit and is more competitive than all commercially available Buffalograsses, other than Prairie. 609 Buffalograss provides an attractive, wear tolerant turf which requires less water, fertilizer and mowing than other turfgrass species. These characteristics, along with on-site testing, having shown that 609 Buffalograss is well adapted to golf course roughs, home lawns, and institutional areas requiring a reduced management level.
A single plant of the genotype 609 Buffalograss was selected from a nursery of plants. The nursery of plants from which the selection was made was grown from a single female plant designated TAES 1321.1. This nursery was not maintained after 1984, in Texas and the germ plasm was transferred to Nebraska. The single female plant TAES 1321.1 had been selected from a field grown from seed. The seed was from an open pollinated hybridization nursery of: (1) a plant found in a native stand in 1980 in Austin, Tex. designated TAES 1321; and, (2) 149 other native ascessions.
This female genotype was found in a plot labeled 1321.1 which was originally collected in Austin, Tex. This selection was identified as NE 84-609 and evaluated at the John Seaton Anderson Turfgrass Research Facility near Mead, Nebraska. The female genotype was propagated vegetatively by stolons and pre-rooted plugs to provide planting stock for studying performance and making comparisons to "Texoka", a commercial standard; "Prairie", a new release from Texas A&M.

FIG. 6 is a photograph of a NE 84-609 plant.
The excellent overall turfgrass quality, rate of establishment, good cold tolerance, high density and drought tolerance of Buffalograss along with other information allow this genotype to be distinguished from other Buffalograsses. Vegetative propagation of 609 Buffalograss from plugs or sod pieces permits maintenance of cultivar with no genetic variation.
Gentotype Buffalograss is a female plant from a dioecious species which has a yellow anther color. The growth characteristics of buffalograss can be used to distinguish one cultivar from others. 609 Buffalograss, Prairie, Texoka and the Nebraska experimentals are all female clones, but eventually male clones will be developed.
The internodes of 609 Buffalograss are similar to "Texoka" in width, but longer in length (Table 1). The length of internode one of 609 Buffalograss is longer than NE 84-315 and NE 84-378, but internode widths are all the same. The tiller leaf blade width is similar to "Texoka" and other experimentals, but the tiller leaf blade length is much smaller for all tillers measured (Tables 2 and 3). Measurements of the spikelet and length indicate that Buffalograss has a shorter spikelet than the standard "Texoka" (Table 4). At the UNL research facility, 609 Buffalograss produced more, lower growing inflorescences than Texoka or NE 84-315. 609 Buffalograss had inflorescences comparable to NE 85-378; however, its canopy is medium and NE 85-378 is open (Table 5).
609 Buffalograss has been evaluated at several locations throughout the United States. In most tests 609 Buffalograss was compared to "Texoka" a commercial standard; "Prairie" a new release from Texas A&M; and other experimentals which are being considered for release.
609 Buffalograss had an excellent rate of establishment (Tables 6 and 7). The Texas A&M-Dallas trial shows that 609 Buffalograss and "Prairie", both well adapted to the deep South, had better establishment than "Texoka" or other Nebraska selections. The Southern Illinois study indicated that 609 Buffalograss showed slower establishment than the better adapted northern selections, and was more sensitive to over applications of Princip® (Table 8). Stolen production and stolon length at Texas A&M-Dallas showed that 609 Buffalograss produced more stolons and larger stolons than "Texoka" or other Nebraska selections (Table 9). At Nebraska, 609 Buffalograss exhibited excellent establishment in all plantings, including increases of material for plant breeders' nurseries and experimental plot area. David Doguet, of Crenshaw & Doguet Turfgrass, Inc., reported that 609 Buffalograss showed slightly faster establishment than "Prairie" buffalograss under sod farm conditions.
The most definitive way to differentiate 609 from "Prairie" is a DNA fingerprint. Work conducted at the University of California-Davis has distinguished 609 Buffalograss from "Prairie" with at least two primers. Primer AO-1 provides a very clear separation of these two cultivars (FIG. 1).
Buffalograss is a warm season species and will green up later and go dormant earlier than cool season species such as Kentucky bluegrass. Although this characteristic may be a negative in the northern part of the United States, buffalograss may have a longer growing season than other warm season turfgrasses in the South. Spring green-up has been evaluated at both the University of Nebraska and at Texas A&M-Dallas. 609 Buffalograss had a spring green-up rate similar to Texoka in Nebraska and similar to Prairie in Texas (Tables 10 and 11). Although an earlier spring green-up and a later dormancy in the North would be advantageous, it is possible that cold hardiness would be lost. 609 Buffalograss may have slightly less cold hardiness than Texoka when grown in the North.
Turfgrass color is an important component of turfgrass quality. At Texas A&M-Dallas, 609 Buffalograss had color ratings superior to the commercial standards Texoka and Prairie. (Tables 12 and 13).
Turfgrass quality is a rating used to indicate the aesthetic value of a turf cultivar. This characteristic is very important in buffalograss because its turf characteristics have been overlooked in the past. 609 Buffalograss had outstanding turfgrass quality at each location in the South (Tables 14, 15, 16, and 17). In each location, 609 Buffalograss had quality comparable or superior to Prairie, Texoka and Nebraska experimentals. At the University of Nebraska, 609 Buffalograss had turfgrass quality ratings comparable to Texoka in the spring and higher ratings during the summer (Table 18). At the Crenshaw & Douget sod farm, Bastrop, Tex., 609 Buffalograss had an excellent, high quality sod.
Reduced water use and drought stress avoidance are important characteristics of drought resistance in buffalograss, contributing to its lower maintenance cost. 609 Buffalograss has been shown to have drought stress tolerance at University of Arizona (Table 19) and at the University of Nebraska (Table 22). Water use rates of 609 Buffalograss have been comparable to Texoka and Prairie in Nebraska (Table 23). The water use rates of all three cultivars are less than those of other turf species.
Density is an important component of turfgrass quality. In studies at the University of Arizona and at the University of Nebraska, 609 Buffalograss had turfgrass density ratings equal to or better than Texoka (Table 24). This density has permitted 609 Buffalograss sod to be harvested three months after planting at the Crenshaw & Douget sod farm.
