Abstract

I disclose that my herein invention of a new variety of Zoysia grass plant was discovered by me through my cross-pollinating of selected varieties of Zoysia grass plants, then through asexual repropagation I selected the new and distinct variety of Zoysia grass plant ZT-26. This new variety of Zoysia grass plant produces an excellent turfgrass from stolons and rhizomes with a considerably faster establishment growth rate and with a more open texture that develops less thatch and retains superior green color during the winter period when compared to the closest known varieties of the species.

Show the legal claimThe single numbered claim as granted — the legal text that defines what this patent covers.

Having now described the new and distinct variety of Zoysia grass plant ZT-26 which I have discovered and asexually reproduced, I claim: 1. A new and distinct variety of Zoysia grass plant, ZT-26, herein shown and described by a dark yellowish green, as defined by the centroid color chart; this new claimed variety produces a faster establishment growth rate, and a superior green color retention during the winter period, with a more open growth characteristic that produces less thatch build-up; the anthers of the new claimed variety of Zoysia grass plant are pale greenish yellow, as defined by the ISCC-NBS centroid color chart; the stigmas are pale yellow green color, as defined by the ISCC-NBS centroid color chart; the stolons of the new claimed variety of Zoysia grass plant, are wider apart with a light yellow green color, as defined by the ISCC-NBS centroid color chart; the entire plant of the new claimed variety of Zoysia grass plant is glabrous, except for two or three hairs at the top of the sheath at the sides of the ligule, with the ligule a small ciliate fringe; the new claimed variety of Zoysia grass plant, ZT-26, when using the electrophoresis banding pattern method, shows a distinct uniqueness, when compared to the closest known variety of Zoysia grass plant.
