Abstract
An asexually reproduced variety of male or staminate perennial buffalograss distinguished by a unique combination of characters including fine leaf blade width and high tiller number at stolon nodes.
Description
Latin name of the genus and species of the plant claimed: The present invention relates to the genus and species Buchloe dactyloides (Nutt) Engelm.
Variety denomination: ‘MB’.
Field of Invention
The present invention relates to a new and distinct asexually reproduced variety of perennial Buchloe dactyloides (Nutt) Engelm.
This invention relates to a new and distinct perennial male or staminate buffalograss cultivar identified as ‘MB’ (herein referred to as ‘MB’). The inventors, David Doguet and Virginia G. Lehman, discovered ‘MB’ under cultivated conditions in a mowed roadside area near Houston, Tex. ‘MB’ was identified as a distinctly different vegetative male patch or segregated clonal plant differing by much higher tiller density than the surrounding male clones, or any other male clones known in the inventors knowledge. The inventors asexually reproduced ‘MB’ by taking vegetative cuttings of the plant material including stolons and tillers, cutting the stolons into segments, each with a vegetative bud, and rooting them in field nurseries at Bladerunner Farms, Inc. nurseries near Poteet, Tex. Stolons and vegetative plugs of ‘MB’ were asexually reproduced and moved to the greenhouse and field nurseries near Lebanon, Oreg. for further evaluation.
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 Buffalograss plant named ‘MB’.
FIG. 1. Inflorescence of ‘MB’ buffalograss.
FIG. 2. Stolon of ‘MB’ buffalograss.
‘MB’ was characterized in greenhouse and field conditions. ‘MB’ is a unique male or staminate variety of buffalograss (Buchloe dactyloides (Nutt) Engelm.) that was discovered under cultivated conditions in a mowed roadside area near Houston, Tex. ‘MB’ was identified as having a much higher tiller density than the surrounding male buffalograss clones, or any other male clones known in the inventor's knowledge. The mowed roadside was located in USDA Plant Hardiness Zone 9a. ‘MB’ was propagated by the inventors under field and greenhouse conditions in Poteet, Tex. and Lebanon, Oreg. by cutting of stolons, rooting them in soil, and planting of the rooted material to provide planting stock for studying performance and for comparison of morphological characters after propagation. ‘MB’ has been propagated by stolons, tillers, and sod. Asexually reproduced plants of ‘MB’ have remained stable and true to type through successive generations of propagation. No female inflorescence has been noted from ‘MB’, and as a consequence, no seed has been produced from ‘MB’.
‘MB’ is a perennial buffalograss that spreads by stolons and tillers. Characteristics of ‘MB’ measured in 2005 were taken from plants that were approximately 15 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 with a minimum 14-hour day length, supplemented with photosynthetically active radiation equivalent to approximately 50% sunlight. The plants were fertilized with the equivalent of 1 pound of actual N per month, using a soluble fertilizer of 20-20-20 in two equal soluble applications per month.
‘MB’ has a shorter canopy height than ‘609’ U.S. Plant Pat. No. 8,475 (Table 1) when measured under greenhouse conditions in Lebanon, Oreg., 2005. Most significantly, ‘MB’ has more tillers per stolon node than either Prairie or ‘609’, a positive trait when the turfgrass is harvested for sod production. ‘MB’ has shorter internode lengths (Table 2), providing a higher density turfgrass. As a male or staminate clone, no burrs with seeds of ‘MB’ have developed; no seedlings have been noted in field production area or field test areas. The inflorescences produced in the greenhouse have consisted of a staminate structure or male with anthers. The anthers have been observed to shed pollen; it is possible that ‘MB’ would fertilize a receptive female buffalograss but this has not been observed, nor tested. ‘MB’ has retained the unique characters during successive stages of propagation and has shown to be a stable variety in asexual propagation.
‘MB’ has shown susceptibility to buffalograss mite, [Eriophyes slykhuisi (Hall)] in test plots near Poteet, Tex. ‘MB’ has not shown susceptibility to any diseases or other insects such as mealybug. ‘MB’ shows turf density higher than ‘Prairie’ or ‘609’, and when harvested as sod, maintains sod block integrity. ‘MB’ is adapted North/South from the Kansas-Oklahoma border through Mexico, and East/West from Missouri to California. ‘MB’ is similar to most buffalograsses in water use demands, having excellent long term drought survival. ‘MB’ is adapted from sandy to heavier loam soil textures and from slightly acid to slightly alkaline soil pH.
