-------------------------------------------------------------------------------
UA 48 is a high yielding, conventional cotton variety that sets a new standard for fiber quality. A limited amount of seed is being marketed directly to producers by the University of Arkansas Division of Agriculture for the 2011 season. This method of introducing a new variety is in response to demand to help fill the void of high yielding, conventional varieties for growers who are using conventional herbicide programs to manage glyphosate-resistant weeds.
Developed by cotton breeder Fred Bourland at the Division’s Northeast Research and Extension Center at Keiser, UA 48 has ranked among the best transgenic and conventional varieties in tests in the Mid-South in yield and other traits. It has exceptional lint quality and set new standards for length, uniformity index and strength for upland cotton varieties adapted to the Mid-South.
Performance data are from tests at four Arkansas sites, 2007-09; Tennessee and Arkansas Variety Tests, 2009; and strip tests managed by producers in Arkansas, Alabama, Mississippi and Texas. |
