Abstract
An asexually reproduced variety of perennial zoysiagrass with a unique combination of characters including an absence of leaf blade hairs, deep rhizomes, good recovery from sod harvest, high salinity tolerance, good shade tolerance, and a distinct DNA fingerprint.
Description
The present invention relates to a new and distinct asexually reproduced variety of perennial zoysiagrass (Zoysia marrella (L.)) Merr.
This invention relates to a new and distinct perennial zoysiagrass cultivar identified as `Diamond` zoysiagrass (herein after referred to as `Diamond`), which was tested as `DALZ8502`. `Diamond` was discovered and identified at Dallas, Tex., as an aberrant selection in cultivated turf plots that were previously planted to a series of zoysiagrass plant introduction and commercial cultivars, including `Meyer` and `Emerald`. It was identified as a superior turf compared to other zoysiagrasses in its recuperative ability after sod harvest, its shade tolerance and salinity tolerance. `Diamond` is an aggressively spreading Zoysia matrella (L.) Merr. that is appropriate for use in full sun to shaded tee boxes and greens in the coastal states, wherever zoysiagrass is adapted.
For purposes of registration under the "International Convention for the Protection of New Varieties of Plants" (generally known by its French acronym as the UPOV Convention) and noting Section 1612 of the Manual of Plant Examining Procedure, it is proposed that the new variety of zoysiagrass of the present invention be named `Diamond` Zoysiagrass.
FIG. 1 is a photograph of the leaf blade and of the inflorescence of `Diamond`.
FIG. 2 is a DNA fingerprint of `Diamond` in contrast to `Meyer` zoysiagrass.
`Diamond` was characterized in greenhouse and field conditions. `Diamond` is a unique variety of zoysiagrass (Zoysia matrella (L.)) Merr. that was discovered under cultivated conditions described above. `Diamond` was vegetatively propagated and reproduced. `Diamond` has been propagated by sod, plugs, springs, and stolons. Seed reproduction with self-fertility is not common in the Zoysia sp. No seedling establishment from `Diamond` has been noticed in either greenhouse or field studies.
`Diamond` is distinguished from other varieties of zoysiagrass by the combination of characters of shade tolerance, salinity tolerance, and turf quality. `Diamond` is closest in appearance to the variety `Emerald` zoysiagrass. `Diamond` generally lacks winter hardiness such that it is recommended for use south of Red River (Texas-Oklahoma) and in the coastal plain states.
`Diamond` reproduces by rhizomes and stolons. `Diamond` produces rhizomes that grow to a depth of 4-6", depending on maintenance programs. The stolons of `Diamond` have a mean internode length of 6.4 mm between the fourth to the fifth node, 15.5 mm between the second and third nodes, with a mean stolon width and diameter from 0.79 to 0.88 mm (Tables 1, #2). These stolons and rhizomes root adventitiously at the nodes. Color notations of plant tissues were based on the Munsell Color Charts for Plant Tissues, Munsell Color, Baltimore, Md., 1977. Light quality, photoperiod, and general growth of the plants affect color notations. The internode color of `Diamond` stolons exposed to full sun of is 5R 3/4.
Leaf blades of `Diamond` are rolled in the bud, and are flat and stiff. The leaf blade length of `Diamond` ranges from 22.7 to 42.0 mm and from 0.95 to 1.28 mm in width (Table 3, #4, #5), shorter and narrower than `Emerald`, `El Toro`, and `Meyer`. There are not any hairs on the abaxial/adaxial leaf surfaces of `Diamond`. Measured under greenhouse conditions in January 1996, the genetic, adaxial leaf color of `Diamond` is 2.5 GY 5/2 to 2.5 G 5/2, with `El Toro` having a leaf color of 2.5 GY 5/2, and `Meyer` having a color of 2.5 G 3/4. The ligule of `Diamond` is a row of silky hairs, approximately 2.1 to 2.6 mm in length on the longest hairs.
The flag leaf length of `Diamond` is a mean of 3.69 cm when measured in a greenhouse, Dallas, Tex., January 1996. `Diamond` has yellow-green anthers, fading to purple, colored anthers and white colored stigmas, undistinguished in shade of color. The inflorescence of `Diamond` is a terminal spike-like raceme, with spikelets on short pedicels. `Diamond` has a mean culm length of 2.40 cm, a floral region of 9.32 mm, with a mean of 10.3 florets per raceme.
The chromosome number of `Diamond` is 40.
`Diamond` has tremendous sod harvest potential because of its strong rhizome system (Tables 6, #7). In trials at Dallas, Tex., established in 1983 and harvested in 1985 with a sod harvester, `Diamond` showed high recovery in number of plants. `Diamond` showed 22.5 and 93.8 plants per square foot at 19 and 42 days after harvest, respectively. `Emerald` showed only 8.7 and 30.3 plants per square foot, with `Meyer` having only 2.5 and 11 plants after 19 and 42 days, respectively. Compared to `Meyer`, `Diamond` produced 8.5 times more plants, and 3.1 times more plants than `Emerald`. In the practical sod regrowth rates observed under field conditions, where the sod cycle from harvest to harvest averages a 4 month growth cycle, the potential exists to harvest `Diamond` three times over a 24-month time period in North Texas.
With excessive nitrogen fertilizer and its genetically controlled rhizome production, `Diamond` may produce high levels of thatch. Close mowing (less than 12.5 mm) with a reel mower and routine verticutting will be necessary to maintain the highest quality turf with `Diamond`.
`Diamond` was entered in the 1991 National Turfgrass Evaluation Program (NTEP) and was tested at 24 locations across the United States for over 3 years. One test was planted into a sited shaded with live oak trees on 1 Sep. 1992. Under tree shade with competition from trees for available moisture and nutrients, `Diamond` had slightly more cover than `Belair` and `Meyer` (Table 8). In field sites with artifical shade, `Diamond` was significantly improved in shade tolerance over `Emerald` and `El Toro` (Table 9).
When `Diamond` was compared with 57 other zoysiagrasses for salinity tolerance, it ranked number 2 in performance, and first in reduced injury when compared to `El Toro`, `Emerald`, `Belair`, or `Meyer` (Table 10). When compared to other commercial varieties for root growth, Diamond had less total root depth or total root mass, and produced fewer clippings than the other cultivars (Table 11).
