Abstract
I disclose that my herein invention of a new variety of Zoysia grass plant, was discovered by me through my cross-pollination of selected varieties of Zoysia grass plants, then through asexual repropagation, selected the new and distinct variety of Zoysia grass plant ZT-11, which produces an outstanding dark olive green color with a uniform turfgrass surface that has virtually no seedheads with a very upright growth characteristic from stolons and rhizomes, then held complete green color throughout several winter periods. The anthers of the new claimed variety of Zoysia grass plant are dark purplish red color 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 are a very dark red color, as defined by the ISCC-NBS centroid color chart with stolon internodes closer together. The entire plant of the new claimed variety of Zoysia grass plant ZT-11, is glabrous except on the inside of the color just above the ligule where several long hairs are present. The electrophoresis isoenzyme banding patterns show distinct uniqueness of the new claimed variety of Zoysia grass plant designated ZT-11.
