Abstract

A new and distinct cultivar of Miscanthus plant named ‘MBS 7003’, generally characterized by its vigorous growth rate, top leaf height, green-colored leaves, high biomass yield and high tiller density.

Description

Latin name of genus: Miscanthus sp.
Varietal denomination: ‘MBS 7003’, or ‘Columbia’.
BACKGROUND
The present disclosure relates to a new and distinct cultivar of hybrid Miscanthus originated as a cross from Miscanthus sacchariflorus (♀, 4n) and M. sinensis (♂, 2n) plants, and will be referred to hereafter by its cultivar name, ‘MBS 7003’. ‘MBS 7003’ represents a new cultivar of Miscanthus species, a perennial grass which is grown for biomass production, building materials, livestock bedding, landscape use and ornamental value.
The new cultivar MBS 7003 is a fertile M.×giganteus (4×) plant. It is unique to other M.×gigateus cultivars in that in can be propagated by rhizomes, stem, and from seed if pollinated with a different compatible genotype. Details describing its phenotypic and performance identity are indicated herein.
The invention described in this application was derived through the process of botanical plant breeding techniques, phenotypic and genotypic identification, and stability of performance compared to other M.×giganteus type cultivars. Initial breeding work was done at Klein Wanzleben, Germany utilizing the greenhouse for crossing and selection, with subsequent field evaluation. Selection on the clonal propagated genotype was made at Klein-Wanzleben. Additional evaluation occurred in the US upon receiving plant material following successful APHIS regulated importation quarantine process.
‘MBS 7003’, also known as ‘Columbia’, was selected for its vigorous growth from a selection field which was established from seedlings. The seedlings were obtained from seeds of a polycross of Miscanthus sacchariflorus (♀, 4n) and M. sinensis plants (♂, 2n). ‘MBS 7003’ 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 a pollen donors (accession Nos.: 93m0146002, 92M0179020, 92M1079017, 93M0147009, 92M0179016, 93m0146012, 93M0144001, 93m0146017, 92m0086, 92m0179015, 93m0146001, 93M0084, 93m0006005, 93M0006003, and 93m0007212; ploidy: 2×). From this cross, 158 seedlings were obtained and planted in a field. Based on field observations, a tetraploid variety having high biomass was selected and designated as ‘MBS 7003’.
The commercial comparison to ‘MBS 7003’ is M.×giganteus cv. ‘Illinois’. ‘Illinois’ was derived from a similar interspecific cross using different parental genotypes between Miscanthus sacchariflorus (4×) and M. sinensis (2×) resulting in a sterile clone plant selection that is available to the public.
‘MBS 7003’ is different from Miscanthus variety ‘MBS 7001’ (‘Nagara’) disclosed in U.S. Plant Pat. No. 22,033. ‘MBS 7003’ of the present application is 100% fertile, and is approximately 95% to 100% self incompatible and 95% to 100% cross compatible. Miscanthus variety ‘MBS 7001’ (‘Nagara’) is approximately 98% to 100% sterile genotype, and is almost completely self and cross incompatible. Therefore, ‘MBS 7001’ rarely produces seed. In contrast, ‘MBS 7003’ produces significantly higher amounts of seed.
Fertile ‘MBS 7003’ is different from the commercially available M.×giganteus cv. ‘Illinois’ is considered to be a 100% sterile genotype, that is, ‘Illinois’ is completely self- and cross-incompatible.
‘MBS 7003’ is also different from Miscanthus variety ‘MBS 7002’ (‘Lake Erie’) disclosed in U.S. Plant Pat. No. 22,047. ‘MBS 7003’ is shorter in plant height both during the growing season and at seasonal maturity than ‘MBS 7002’.
‘MBS 7003’ is a cross compatible sibling of the Miscanthus variety ‘MBS 1001’ disclosed in the co-pending U.S. Plant patent application Ser. No. 13/067,964. ‘MBS 7003’ is different from ‘MBS 1001’ in that ‘MBS 7003’ has greater vegetative transplanting vigor, and is significantly shorter than ‘MBS 1001’.
‘MBS 7003’ is also different from Miscanthus variety ‘MBS 1002’ (‘MDL 1002’) disclosed in U.S. Plant Pat. No. 22,127. ‘MBS 1002’ is taller, is later flowering and matures later than ‘MBS 7003’. ‘MBS 1002’ has higher seedling vigor than ‘MBS 7003’ upon transplanting, and during spring greenup MBS 1002 has slightly better cold tolerance than ‘MBS 7003’.
‘MBS 7003’ flowers earlier than ‘MBS 7002’ (see U.S. Pat. No. 22,047), ‘MBS 1001’ (see U.S. patent application Ser. No. 13/067,964 filed Jul. 12, 2011), and ‘MBS 1002’ (see U.S. Pat. No. 22,127).
‘MBS 7002’, ‘MBS 7003’, and ‘MBS 1002’ are siblings and recombine very well in crossing.
‘MBS 7003’ 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 7003’ (a.k.a. ‘Columbia’)
The following traits have been repeatedly observed and represent the basic characteristics of the new cultivar. The new cultivar ‘MBS 7003’ 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 following traits in combination distinguish this Miscanthus hybrid from Miscanthus×giganteus cv. ‘Illinois’ and ornamental M. sinensis forms. Plants for the botanical measurements in the present application are two to three-year-old plants. These plants would be considered as mature plants.
    • 1. Vigorous growth
    • 2. Top leaf height about 2.7 meters
    • 3. Green leaves, no colored stripes are present
    • 4. High biomass yield (about 20-30 metric tons per hectare, equals to 9-13 U.S. tons per acre)
    • 5. High tiller density
‘MBS 7003’ 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 7003’ has no stripes or colored bands on its leaves.
In side by side comparisons conducted at Klein-Wanzleben, Germany, ‘MBS 7003’ is more vigorous than either of its parent plants and produces more biomass than either parent. ‘MBS 7003’ has taller culms but demonstrates less lodging; hence, it has stronger culms than the parent phenotypes. The leaves stay longer on the cutin compared to M.×giganteus cv. ‘Illinois’, and therefore, overall leaf loss during the winter is less than M.×giganteus cv. ‘Illinois’.
‘MBS 7003’ can be propagated by rhizomes, from meristem or nodes. This further distinguishes ‘MBS 7003’ from M. sinensis in that M. sinensis cannot be propagated by nodes. ‘MBS 7003’ develops inflorescences and viable seed under optimal growing conditions.

***Refers to that the mean value was calculated based on data collected from 6 locations in one year, therefore 6 total observations were made.
For dry tons per acre feedstock performances over two years and six locations of mature Miscanthus plots, ‘MBS 7003’ was significantly less than sister line ‘MBS 1001’, but similar to the commercial M.×giganteus cv. ‘Illinois’, and sister lines ‘MBS 7002’ and ‘MBS 1001’.
Over six locations in the second year of mature growth ‘MBS 7003’ had significantly smaller basal circumference than commercial M.×giganteus cv. ‘Illinois’, but was similar to its sister lines in comparison. However, ‘MBS 7003’ had significantly greater culm diameter than ‘Illinois’ over the same five locations.
‘MBS 7003’ is significantly shorter by measurement of culm length compared to all sister lines and commercial variety ‘Illinois’.
Flower maturity ratings indicated ‘MBS 7003’ as being significantly earlier than its sister MBS lines and the commercial ‘Illinois’.
Yield:
The average yield of ‘MBS 7003’ compared to Miscanthus×giganteus cv. ‘Illinois’ is provided below in Table 2. Although there was virtually no statistical significance between ‘Illinois’ and ‘MBS 7003’ for feedstock yield, the two locations demonstrated that ‘MBS 7003’ was consistently higher in yield than the commercially available variety.
