Latin name of genus: Miscanthus sp.
Varietal denomination: ‘MBS 1002’.
BACKGROUND
The present disclosure relates to a new and distinct cultivar of hybrid Miscanthus originated as a cross from Miscanthus sacchariflorus (♀, 4n)×M. sinensis (♂, 2n) plants and will be referred to hereafter by its cultivar name ‘MBS 1002’. This cultivar represents a new cultivar of Miscanthus species, a perennial grass which is grown for biomass production, landscape use, ornamental value, and cold tolerance.
‘MBS 1002’ was selected for its vigorous growth from a selection field which was established from seedlings. The seedling of the cultivar was obtained from seeds of a polycross of Miscanthus sacchariflorus (♀, 4n) and M. sinensis (♂2n) plants. ‘MBS 1002’ was generated by crossing a single large-stemmed M. sacchariflorus genotype from Japan (accession No.: 93M0005064, ploidy: 4×) as a female parent with a population of 15 M. sinensis plants as pollen donors (accession Nos.: 93m0146002, 92M0179020, 92M0179017, 93M0147009, 92M0179016, 93m0146012, 93M0144001, 93m0146017, 92m0086, 92m0179015, 93m0146001, 93M0084, 93m0006005, 93M0006003, 93m0007212, and 93M0013004; ploidy: 2×). From this cross, 158 seedlings were obtained and planted in a field. Based on field observations, one tetraploid variety having high biomass was selected and designated as ‘MBS 1002’.
‘MBS 1002’ is different from Miscanthus variety ‘MBS 7001’ disclosed in the co-pending application U.S. Plant patent application No. 12/387,444. ‘MBS 7001’ is an about 98% to 100% sterile genotype, and is almost 100% self and cross incompatible. ‘MBS 7001’ rarely produces a seed and is nonviable. In contrast, ‘MBS 1002’ is 100% fertile, about 98% self incompatible, and 100% cross compatible. ‘MBS 1002’ does produce viable seed.
‘MBS 1002’ is similar to ‘MBS 7002’ disclosed in the co-pending application U.S. Plant patent application Ser. No. 12/387,429, in that it is a fertile, 4× polyploidy derived from the same M. sacchariflorus female and 15 M. sinensis male plants. ‘MBS 1002’ and ‘MBS 7002’ are half-sibs to each other with known female parent. Feedstock yields are similar for both lines (Tables 1-3). They are siblings and recombine very well together in crossing for producing seed.
According to two and three year data and observations, the two cultivars are different from each other for at least the following characters: (1) ‘MBS 1002’ is different from ‘MBS 7002’ in that ‘MBS 1002’ has greater plant vigor during propagation and field transplanting; (2) ‘MBS 1002’ propagation output is 2 times faster than ‘MBS 7002’: When MBS 1002 rhizome propagation is utilized for clonal increase its growth rate from dormant rhizome stage to emerging above ground shoot-leaf stage it is 2× faster than MBS 7002. This is reference to vegetative propagation from rhizomes and not seed. Similar response comparison has been observed with tissue culture propagated plants; (3) ‘MBS 1002’ expresses earlier field spring green up following dormancy; (4) ‘MBS 1002’ has slightly better cold tolerance than ‘MBS 7002’; (5) ‘MBS 1002’ expresses similar basal circumferences at maturity, but individual culm diameter is significantly greater for ‘MBS 1002’ over ‘MBS 7002’ and the check variety ‘Illinois clone’. As a result of this last difference, ‘MBS 1002’ has significantly greater compression circumference than ‘MBS 7002’ and ‘Illinois clone’ (Table 4).

The plant was established asexually from sterile rhizome buds in Klein-Wanzleben, Germany by the inventor. The shoot material was propagated on rooting media and the rooted plantlets were planted into pots in the greenhouse. The plants were planted into the field after one cold period. The characteristics of this cultivar have been determined to be stable and are reproduced true to type in successive generations.
SUMMARY
‘MBS 1002’ (a.k.a. ‘MBS 7005’ or ‘MBX 006’)
The following traits have been repeatedly observed and represent the characteristics of the new cultivar. The new cultivar ‘MBS 1002’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in temperature, day-length, light intensity, soil types, and water and fertility levels without, however, any variance in genotype. The color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition.
The following traits have been repeatedly observed and are determined the basic characteristics of ‘MBS 1002’, which in combination distinguish this Miscanthus hybrid from the known Miscanthus×giganteus and other ornamental M. sinensis forms. Plants for the botanical measurements in the present application are two and three-year-old plants. These plants would be considered as mature plants.
    • 1. Vigorous growth
    • 2. Top leaf height about 2.6 meters
    • 3. Green leaves, no colored stripes are present
    • 4. High biomass yield
    • 5. High tiller density
‘MBS 1002’ (a.k.a. ‘MBS 7005’ or ‘MBX 006’) can be distinguished from the Miscanthus cultivars ‘Strictus’ (not patented, a.k.a ‘Porcupine grass’), ‘Super Stripe’ (U.S. Plant Pat. No. 18,161), ‘Gold Bar’ (U.S. Plant Pat. No. 15,193), ‘Little Zebra’ (U.S. Plant Pat. No. 13,008) and ‘Mysterious Maiden’ (U.S. Plant Pat. No. 16,197) in that ‘MBS 1002’ has no stripes or colored bands on its leaves.
The plant can be propagated by rhizomes, from meristem or nodes. This further distinguishes ‘MBS 1002’ from M. sinensis in that M. sinensis cannot be propagated by nodes. ‘MBS 1002’ aka ‘MBS 7005’, was selected for its vigorous growth from a selection field which was established from seedlings. It is propagated as a single plant and is used as a parent use for seeded varieties. It can be propagated from Rhizomes and will be utilized as main parent for the described MBS F1/Syn1 cultivars. (See Tables 1-10 for performance and comparisons to other cultivars and the check variety M. giganteus, cv. ‘Illinois Clone’). The plant was established asexually from rhizome buds at Klein-Wanzleben, Germany by the inventor company. The shoot material was propagated on rooting media and the rooted plantlets were planted into pots in the greenhouse. The plants were planted into the field after one cold period. The characteristics of this cultivar have been determined to be stable and are reproduced true to type in successive generations.

  • Growth and propagation:
      • Propagation.—By culm division, in vitro culture, from rhizomes, meristem or axillary buds (nodes).
      • Growth rate.—Vigorous.
        The following descriptions are based on data from 2-3 year old plants, which are considered mature plants.
  • Culm (stem) description:
      • General description.—Cylindrical, pithy, reed-like, erect, sheathed. 15-17 leaves per culm.
      • Culm aspect.—Rigid and held erect, none are cascading.
      • Culm color (dormant season).—Yellowish, lower internodes partly reddish brown/orange (RHS 167B-167C). Midsummer color is green to dark green (RHS 144A-146B) in Germany and the US; end of season is brown. End of season culm color in the US-Lafayette, Ind. to Southern GA range is RHS 164B at culm base to 162D at culm top past final node; lower internodes predominantly red-pink to violet (RHS N77B) with some green (RHS 144A-146C), and vary with intensity depending on location and growing conditions. The rate at which the culm color changes is dependent on location, with the change from green to dormancy brown as described herein being more rapid in the northern latitudes when the days become increasingly shorter.

M.×giganteus is also a cross between M. saccharaflorus (4×) and M. sinensis (2×) resulting in a sterile clone plant selection that is available to the public. This is how ‘MBS 1002’ was derived, only using different parentage in the ploy-cross as described. Therefore M.×giganteus (3×) cv ‘Illinois clone’ is an excellent cultivar for comparison with novelty claims.
