Narrative
Chisholm summer-dormant (SD) tall fescue is a forage type, synthetic cultivar developed from phenotypic selections for persistence made in southern Oklahoma and north Texas from the cultivar Flecha. Chisholm tall fescue is a Mediterranean or SD ecotype characterized by increased growth in mild winters and dormancy during hot and dry summers. Chisholm differs from the Mediterranean cultivar Flecha by possessing a later heading date (4 days) and a more erect growth habit. Plants of Chisholm have wider flag and tiller leaf widths of 0.4 and 0.8 mm, respectively when compared to plants of Flecha. When tested in small plot grazing trials for persistence in southern Oklahoma and north Texas from 2011–2016, final stands of Chisholm were 23% greater than Flecha and the Mediterranean cultivar Prosper when averaged across all locations, which was the justification for release. Chisholm is capable of producing high quality pasture from autumn through spring, thereby providing a perennial forage option for livestock producers to complement or replace the planting of winter annuals such as dual-purpose wheat.
