In 2003-2004, a new Roundup ReadyŽ ETQ (Enhanced Turf Quality) Kentucky bluegrass study was initiated. The trials on fairway and green conversion with Roundup ReadyŽ creeping bentgrass are in their second year. Morphological and genetic characterization of a number of alternative turfgrass species, including Poa trivialis, colonial and velvet bentgrass is in progress. The field study of winter hardiness of perennial ryegrass is in its second year. An important gene potentially responsible for freezing tolerance has been isolated from perennial ryegrass and further studies on its function are underway.
New fairway height creeping bentgrass, green height creeping bentgrass, and fine fescue studies were established in the fall of 2003. These plots will be on the field day program on July 22, 2004. New display areas for the Iowa Golf Course Superintendents Association, the Iowa Sports Turf Manageres Association, and the Iowa Professional Lawn Care Association were also completed for use at this field day this year.
We would like to acknowledge Will Emley, superintendent of the ISU Horticulture Research Station; Rodney St. John, manager of the turf research area; Federico Valverde, research associate; Chris Blume, undergraduate research associate; Dr. Young Joo, visiting scientist; Luke Dant, Mark Howieson, Marcus Jones, Yanwen Xiong, S.K. Lee, and Jason Kruse, graduate students; and all others employed at the field research area in the past year for their efforts in building the turf program.
Special thanks to Mark Hoffman and Sherry St. John for helping to prepare this publication.
