| Abstract/Contents: | "Reduced-growth, Roundup® Ready Kentucky bluegrass (Poa pratensis L.) was recently developed by The Scotts Company and the Monsanto Company. There has been no comparative analysis done with new transgenic lines of Kentucky bluegrass versus reference cultivars, or tissue culture control lines to determine vegetative character similarities and differences. This study measured the vegetative characteristics of the transgenic lines, tissue culture control lines, and reference cultivars in two locations, Ames, Iowa and Madison, Wisconsin, USA over a two year period in order to evaluate the vigor and competitiveness of the transgenic lines. The study was conducted in a mown, competitive setting (plugs of the tested Kentucky bluegrass overseeded with fine fescue, Festuca spp.). Data collection for vigor and competitiveness included rhizome proliferation and total plant area. Transgenic lines in Iowa exhibited 21% less rhizome spread and 34% less colony area than reference cultivars. The transgenic lines exhibited 31% less rhizome spread and 47% less colony area than the tissue culture control lines. Transgenic lines in Wisconsin exhibited 11% more rhizome spread and 20% more colony area than reference cultivars, while the transgenic lines exhibited 16% less rhizome spread and 22% less colony area than the tissue culture control lines. Transgenic line Tx01-2900 showed the most promise for commercialization, while Bx01-5609 showed the least." |
