BACKGROUND OF THE INVENTION
Field of Invention
The present invention relates to a new and distinct asexually reproduced variety of perennial zoysiagrass (Zoysia matrella (L.)) Merr.
BRIEF SUMMARY OF THE INVENTION
This invention relates to a new and distinct perennial zoysiagrass cultivar identified as ‘M66’ zoysiagrass (herein referred to as ‘M66’). The inventors, David L. Doguet, Daric Doguet, and Virginia G. Lehman, discovered ‘M66’ under cultivated conditions near Poteet, Tex. in a collection of seedling plants. The seedling plants originated from proximity cross among ‘Zeon’ (U.S. Plant Pat. No. 13,166), ‘L1F’ (U.S. Plant Pat. No. 25,203), ‘29-2 B9’ (unpatented), and ‘380-1’ (unpatented). ‘M66’ was identified in 2011 as a distinctly different vegetative patch or clonal plant differing from the surrounding plants. ‘M66’ showed a medium-fine leaf texture, with a dark green color, both finer and darker than ‘Zeon’ (U.S. Plant Pat. No. 13,166). The inventors asexually reproduced ‘M66’ by taking vegetative cuttings of stolons and rhizomes, cutting the rhizomes and stolons into segments, each with a vegetative bud, and rooting them in potting media. ‘M66’ zoysiagrass will be used as a turfgrass suitable for home lawns, sports fields, and golf courses.
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 title of the invention is Zoysiagrass plant named ‘M66’.

 COMPLETE BOTANICAL DESCRIPTION OF THE VARIETY
‘M66’ was characterized in greenhouse and field conditions. ‘M66’ is a unique variety of zoysiagrass (Zoysia matrella (L.)) Merr. that was discovered under cultivated conditions. The inventors, David L. Doguet, Daric Doguet, and Virginia G. Lehman, discovered ‘M66’ under cultivated conditions near Poteet, Tex. in a collection of seedling plants. The seedling plants originated from proximity cross among ‘Zeon’ (U.S. Plant Pat. No. 13,166), ‘L1F’ (U.S. Plant Pat. No. 25,203), ‘29-2 B9’ (unpatented), and ‘380-1’ (unpatented). Both unpatented plants originated from field grown open pollinated crosses between ‘VJay’ (unpatented), ‘6136’ (U.S. Plant Pat. No. 17,808), and ‘JaMur’ (U.S. Plant Pat. No. 13,178) zoysia plants. The seed was combined from the four parents, each individual seed was planted in a pot, and plants from the seed were subsequently transplanted to the field. ‘M66’ was identified in 2011 as a distinctly different vegetative patch or clonal plant. ‘M66’ differed from the surrounding plants in a finer leaf texture and darker green color than ‘Zeon’ (U.S. Plant Pat. No. 13,166). In the plantings near Poteet, Tex., ‘M66’ is a darker green turf than potential parent ‘29-2-B9’. ‘M66’ is closer in color to ‘380-1’ but has a finer leaf texture than both ‘380-1’ and ‘29-2-B9’.
The plants were located in USDA Plant Hardiness Zone 8. The inventors asexually reproduced ‘M66’ in both Poteet, Tex. and Lebanon, Oreg. by taking vegetative cuttings of stolons and rhizomes, cutting the rhizomes and stolons into segments, each with a vegetative bud, and rooting them in potting media. Planting of the rooted material provided planting stock for studying performance and for comparison of morphological characters after propagation. ‘M66’ has been propagated by rhizomes, stolons, tillers, and sod. Asexually reproduced plants of ‘M66’ have remained stable and true to type through successive generations of propagation. No seedling establishment from ‘M66’ has been noticed in either greenhouse or field studies.
‘M66’ is a perennial zoysiagrass that spreads by both stolons and rhizomes. Characteristics of ‘M66’ measured in 2015 and 2017 were taken from plants that were approximately 12 months in age. The greenhouse was located near Lebanon, Oreg., with a nighttime low temperature of 50 degrees F., and daytime high of 80 degrees F., and a minimum soil temperature of 77 degrees F. The plants were grown under natural daylength without supplemental lighting. The plants were fertilized with the equivalent of 1 pound of actual N per month, using a soluble fertilizer of 20-20-20 in four equal soluble applications per month.
‘M66’ has a medium-fine leaf texture, with a wider leaf than ‘Diamond’ (Table 1). ‘M66’ has a finer leaf than ‘29-2 B9’ and ‘380-1’, both of which were possible parents in the original cross (Table 4). ‘M66’ has sparse to absent leaf hairs except for a very few long hairs versus ‘Zorro’, which has many leaf surface hairs (Table 2). ‘M66’ has a thicker youngest stolon node and 1-2 stolon internode lengths not different from ‘Diamond’ (Table 3). ‘M66’ shows darker green color than ‘Zeon’ or ‘L1F’ when maintained in turf plots (Table 6).
‘M66’ has shown moderate resistance to brown patch when grown in California. ‘M-66’ rated a 3.8 (where 9=heavy disease symptoms) when Zorro rated 1.8; ‘L1f’ rated a 2.7; Zeon rated 6.3; ‘Palisades’ rated 1.5, all with a 1 sd (p=0.05) of 1.3. In addition, in greenhouse conditions, ‘M-66’ has shown susceptibility to zoysia rust (Puccinia species). ‘M66’ has not shown susceptibility to the zoysiagrass mite when tested at Poteet, Tex., where susceptible varieties have shown the coachwhip leaf symptoms of the mite. ‘M66’ has shown good turfgrass performance and temperature adaptation when tested as far north as Athens, Ga., USDA hardiness zone 8a, which would extend the area of adaptation for ‘M66’ in a line from northern Georgia across central Texas in an East/West line and on a North/South line from Atlanta, south through Mexico. ‘M66’ will be limited only by winter survival in colder regions. ‘M66’ is similar to most medium textured zoysiagrasses in water use demands as shown in test situations near Poteet, Tex., ‘M66’ is adapted from sandy to heavier loam soil textures and from slightly acid to slightly alkaline soil pH.

COMPLETE BOTANICAL DESCRIPTION OF THE VARIETY
  • Origin: ‘M66’ is a cultivar of a single clone discovered under cultivated conditions in a Poteet, Tex. planting of zoysiagrass clones derived from a collection of seedling plants originating from proximity cross among ‘Zeon’ (U.S. Plant Pat. No. 13,166), ‘L1F’ (U.S. Plant Pat. No. 25,203), ‘29-2 B9’ (unpatented), and ‘380-1’ (unpatented). Both unpatented plants originated from field grown open pollinated crosses between ‘VJay’ (unpatented), ‘6136’ (U.S. Plant Pat. No. 17,808), and ‘JaMur’ (U.S. Plant Pat. No. 13,178) zoysia plants. The seed was combined from the four parents, each individual seed was planted in a pot, and plants from the seed subsequently transplanted to the field. ‘M66’ was identified in 2011 as a distinctly different vegetative patch or clonal plant. ‘M66’ showed a medium-fine leaf texture with a dark green color, both finer and darker than ‘Zeon’ (U.S. Plant Pat. No. 13,166). In the plantings near Poteet, Tex., ‘M66’ is a darker green turf than potential parent ‘29-2-B9’. ‘M66’ is closer in color to ‘380-1’ but has a finer leaf texture than both ‘380-1’ and ‘29-2-B9’.
  • Classification: Zoysia matrella (L.) Merr.
  • Growth habit: ‘M66’ is a perennial plant that spreads by stolons and rhizomes and produces a dense, medium-fine textured turfgrass. The inflorescence of ‘M66’ is a terminal spike-like raceme, with spikelets on short pedicels.
  • Leaf blade: Rolled in the bud, flat surface.
  • Leaf blade pubescence: Sparse to few leaf hairs on the adaxial surface, 1.5 mm long.
  • Leaf margin pubescence: Barbellate margins. ‘Palisades’ has some barbellate margin to a small degree, but not as prominent or regular as M66.
  • Leaf sheath pubescence: Absent except for long hairs at mouth of sheath, 1.2 to 2.5 mm in length; ‘LR1’ mean length sheath mouth hairs: 1.7 mm; Diamond 1.0 mm.
  • Leaf sheath stem attachment: Ring of short hairs are present inside the sheath where it attaches to the stem, 0.2 mm in length.
  • Leaf blade margin: ‘M66’=slight roughness.
  • Leaf blade veins: Prominent under 10× magnification.
  • Leaf blade flexibility (softness): Medium stiff.

      • Flag leaf width.—‘M66’: 1.9 mm.
  • Mature plant height, including inflorescence: 6.5 to 7.5 with a mean of 7.0 cm.
  • Color notations, vegetative characters, based on The R.H.S. Colour Chart (light quality, photoperiod, and general growth of the plants affect color notations):
      • Leaf blade color adaxial leaf surface.—137A green.
      • Leaf blade color abaxial leaf surface.—137A green.
