ZT-4

I claim: 1. A new and distinct variety of Zoysia grass plant herein shown and described by a deep yellowish green color, as defined by the ISCC-NBS centroid color chart; this new claimed variety of Zoysia grass plant ZT-4 produced an excellent uniform turfgrass surface, which held complete green color throughout two randomized replicated trial winter periods, when compared to the closest known variety of Zoysia grass plant ZT-26, which lost 25% to 30% of green color throughout those two trial periods; this new claimed variety of Zoysia grass plant ZT-4 also produced a 40% to 50% greater stolon and rhizome growth rate at low winter temperatures, when compared to the closest known variety of Zoysia grass plant ZT-26; the anthers of the new claimed variety of Zoysia grass plant are pale yellow color, as defined by the ISCC-NBS centroid color chart; the stigmas are yellowish white color, as defined by the ISCC-NBS color chart; the stolon internodes of the new claimed variety of Zoysia grass plant are closer together and thinner in width than the closest known variety of Zoysia grass plant ZT-26; the entire plant of the new claimed variety is glabrous except on the upper leaf surface which is sparsely pubescent and on the inside of the collar, just above the ligule, where several long hairs are present; and the new claimed variety of Zoysia grass plant ZT-4 shows distinct uniqueness with the electrophoresis isoenzyme banding pattern methods, when compared to the closest known variety of Zoysia grass plant ZT-26.
