Description

LATIN NAME OF THE GENUS AND SPECIES OF THE PLANT CLAIMED
The present invention relates to the genus Zoysia japonica, species ‘Himeno’.
BACKGROUND OF THE INVENTION Field of Invention
The present invention relates to a new and distinct asexually reproduced variety of perennial Zoysiagrass (Zoysia japonica).
SUMMARY OF THE INVENTION
This invention relates to a new and distinct variety of Zoysiagrass plant that was discovered by the inventor growing among other cultivated Zoysiagrass varieties in the inventor's lawngrass collection in Hiroshima, Japan. This new variety of perennial turf grass possesses a unique combination of desirable qualities such as slow vertical growth, minimal headings and a bluish deep green color.
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 sections 1612 of the Manual of Patent Examining Procedure, it is proposed that the new variety of Zoysiagrass of the present invention be named “‘Himeno’ Zoysiagrass.”
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a color photograph depicting the leaf blades of ‘Himeno’, which exhibit a bluish deep green color of 10GY5/6 using the Munsell Color System. The leaf blade is flat, with a round bottom and gradually tapers to an acute point. The first mature leaf is 3.8-4.9 millimeters in width and 3.0-4.5 centimeters long.
FIG. 2 is a color photograph depicting the spikes of ‘Himeno.’ The spike contains stigmas of yellowish white color of 1GY9/1 using the Munsell Color System. The glumes are 2.3 millimeters long and are reddish brown color of 7R2.5/6 using the Munsell Color System.
FIG. 3 depicts DNA testing of ‘Himeno’ and other Zoysiagrass varieties using CMN-B42 Primer.
FIG. 4 depicts DNA testing of ‘Himeno’ and other Zoysiagrass varieties using CMN-B46 Primer.
DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
‘Himeno’ was discovered growing in the inventor's Miyachi and Yano Collection in Hiroshima, Japan. Specifically, ‘Himeno’ was discovered growing in a pot as progeny of one of five strains of Zoysia japonica which the inventor had previously collected from Yaku Island, which is located in the southern portion of Kyushu, Japan with a latitude of 30.2 degrees north and a longitude of 130.4 degrees east. As measured from 1980 to 1999, the yearly average temperature of Yaku Island is 19.2° C. and the yearly average rainfall is 4501 mm. The soil type of the land where ‘Himeno’ was found is a sandy-loam soil.
After collecting the five strains from Yaku Island, the inventor placed each of the five strains of Zoysia japonica in individual pots in the “Miyachi and Yano Collection,” which is a nursery and research facility specializing in varieties of Zoysia japonica. The five pots were numbered and the origin of the Zoysiagrass was noted. Although the five strains of Zoysiagrass retrieved from Yaku Island all are strains of Zoysia japonica, none of them have variety names since they were existing in an uncultivated state and have not been commercialized. The five strains brought back from Yaku Island each exhibited a very large plant height and a deep yellowish green color, while ‘Himeno’ is much shorter and has a bluish deep green color. Two of the five strains brought back from Yaku Island were unable to survive and deteriorated. ‘Himeno’ emerged from one of these two deteriorated pots. The three surviving strains were designated as ‘J-29’ (not patented), ‘J-30’ (not patented) and ‘K-1’ (not patented).
‘Himeno’ was discovered growing in sandy-loam soil native to Hiroshima in a pot in the Miyachi and Yano Collection. The location of the Miyachi and Yano Collection has an average mean temperature of 11.5° C. and receives an average of 1.46 meters of rainfall annually. Temperature extremes may approach −10° C. and 33° C. The location of the Miyachi and Yano Collection is 580 meters above sea level.
After discovery, the inventor asexually reproduced ‘Himeno’ by cutting stolons and rhizomes, rooting them in soil and planting the rooted material to provide planting stock for studying performance and for comparison.
This newly discovered variety of Zoysiagrass is a perennial that exhibits an attractive and striking bluish deep green color, slow vertical growth, minimal headings, low temperature hardiness, low vertical growth, stable growth, and durable stolon. The most distinguishable characteristics of ‘Himeno’ are its bluish deep green color, slow vertical growth, and minimal headings.
‘Himeno’ is a durable turf grass well suited to recreation areas and requires less maintenance in comparison to other popular Zoysiagrass varieties such as ‘Meyer’ (not patented) and ‘Emerald’ (not patented). The leaf is very short and dense. The stolon is relatively thick and very tough compared to other Zoysiagrass. The grass exhibits very good tolerance to wear and consolidation. It is also quick spreading and has minimal water and fertilizer requirements. The low plant height of ‘Himeno’ reduces mowing frequency. Thus, ‘Himeno’ is well adapted to use in sports fields, parks and for water and wind erosion control.
FIG. 3 depicts DNA testing of ‘Himeno’ and other Zoysia varieties using the RAPD method and CMN-B42 Primer. FIG. 4 depicts DNA testing of ‘Himeno’ and other Zoysia species using the RAPD method and CMN-B46 Primer. In each testing, template DNA was extracted from the mature leaves of ‘Himeno’, ‘J-29’, ‘J-30’, ‘K-1’, ‘Meyer’, ‘Victoria’ (U.S. Plant Pat. No. 9,135), ‘El Toro’ (U.S. Plant Pat. No. 5,845), ‘Miyako’ (U.S. Plant Pat. No. 10,187), ‘Emerald’, Zoysia matrella, Zoysia tenuifolia, and Zoysia macrostachia and was replicated with primer using PCR techniques. The amplified products were electorophoresised on agarose gel, stained and photographed. As can be ascertained from the DNA testing, ‘Himeno’ is distinguishable from the three strains retrieved from Yaku Island (J-29, J-30 and K-1) and the above mentioned Zoysiagrass varieties.
The ‘Himeno’ plant in FIGS. 1 and 2 is about seven (7) years old. The ‘Himeno’ plant emerged from a pot containing a deteriorated strain of Zoysia japonica collected from Yuka Island in 1992. The photographs of FIGS. 1 and 2 were taken in 1999.
A detailed description of the ‘Himeno’ Zoysiagrass:
