Select the tab for the type of search. Each tab has everything you need to do to perform that type of search.

(Results of more than 500 will not return images.)

This search will show only accessions that have material that may be requested, including those not seasonally available.
You may list accessions with separators (commas or semicolons, as shown below) or by entering them on separate lines, such as
PI 651794
PI 651649
PI 651650
When searching a range of accessions, use the Advanced Search tab with the Accession Identifier Range criterion.

The more information you provide, the better the search will be.

0PI 648217T 18Paspalum notatum Flüggé Georgia, United StatesS92007DEVELOPED2007Breeding materialT 18 and T 23 bahiagrass germplasm lines have larger more erect plant phenotypes with higher individual plant yields than standard Pensacola. They have value as parents in development of high yielding bahiagrass cultivars for pasture and hay production. Individual plant dry matter yield, plant height and plant diameter were all significantly greater (p= 0.05) than Pensacola bahiagrass when compared in replicated field studies of plants spaced 18 cm apart (Table 1) which supports previous data (Pedreira and Brown, 1996; Werner and Burton, 1991). Plants of T18 and T23 had a more erect plant ideotype than Pensacola or Tifton 9 (Burton, 1989) bahiagrasses. Mature plants of T18 and T23 had significantly fewer culms (8.0 and 6.3, respectively) than Tifton 9 (9.2) in field comparisons of 100 individual spaced plants in 2005. Culm angles from horizontal or prostrate (i.e. 0 %) were significantly greater for T18 (46o) and T23 (55o) than for Tifton 9 (34 o) indicating the more erect plant type. Plant heights and leaf lengths were greater for T18 and T23 than Tifton 9. However, leaf width of the germplasm lines were less than Tifton 9. Flower heads have generally three racemes. Raceme lengths of T18 and Tifton 9 were similar, whereas T23 racemes were shorter. 1728159PI 648217
