Ed Diploid Annual Ryegrass

EdLogo
  • Impressive Cold Tolerance
  • Exceptional Rust Resistance
  • Great Digestibility/Feed Value
  • High Forage Yields

Meet Ed… a newer diploid annual ryegrass out of the University of Florida selected for improved crown rust, cold tolerance and high yield. Ed has been in numerous trials throughout the South since 1999, where it has out-performed many other diploid and Tetraploid varieties.

Cold Tolerance – Unseasonable cold periods can result in plant damage, and sometimes lower yields. According to data from Texas, Nebraska and Florida, Ed has shown improved cold tolerance and resistance to extended periods below freezing. Ed is a survivor!

Crown Rust Resistance – As many producers know, Crown rust (Puccinia coronata) can greatly reduce forage production. Ed diploid annual ryegrass has been specifically bred by the University of Florida to be resistant to Crown rust. Recent test data from Texas confirms that the breeders succeeded. In Overton and Beaumont Texas, Ed scored better in crown rust resistance 50 times against other varieties, and was equal to other varieties 26 times! Only 5 varieties had a higher resistance score, and that was in one location. All 5 varieties had equal resistance scores in the other location. Ed is disease resistant!

Yield Data

High Yield – Ed is a producer! A high yielding variety means greater tonnage, faster animal gains, and the ability to increase stock density. Ed has been trialed in over 25 locations throughout the South, consistently showing above average yields.

From the University of Florida's Fall 2004 Forage Update (complete report):
"Recommended varieties are Jumbo, Florlina, Surrey, Jackson, Magnolia, Rio, Gulf, Southern Star, Big Daddy, TAM 90, Passeral Plus, Ed, Brigadier, Surrey II, Stampede, Fantastic, Graze-N-Gro, King, Prine, and Beefbuilder III. (Other new varieties may be suitable but have not been adequately tested in Florida.)" SIDEBAR
