  1. Yield and fiber quality of UA48 4 locations and 4 years (2007-10) of Strain Tests in Ark. (UA 48, patent and PVP pending) 2-year (2009-10) mean lint yield of DP 393 over all locations was 10th out of 32 varieties in Ark. Cotton Variety Test; UA48 was 24 lb/a less than DP 393. UA48 ArkansasSilk

  2. Yield component variables for UA48 4 locations and 4 years (2007-10) of Strain Tests in Ark. (UA 48, patent and PVP pending) *Based on these results and other performance data, AAES made agreement with West Gaines Delinting to increase seed in 2010.

  3. 2010 Seed Increase of UA48 • About 70 acre field near Whiteface, TX. • Very good production year for west Texas. • Lint yield = 2.2 bales/acre • Little or no field deterioration of seed. • Processed by West Gaines Delinting Company

  4. 2010 Seed Increase of UA48 • Resulting seed quality: • High warm germination, 80-90% • High tetrazolium test, over 90% • Low cold test germination, 35-45% Cotton Seed Quality Curve

  5. Hot water test – UA48 seed from 2010 TX increase • Attempts to break “hard dormancy”: • 85C for 2 minutes • Freezer for 1 and 2 weeks • Soak 15 and 30 minutes then dry • Tumble in metal mixer for 4 and 8 hours

  6. Germ. of dormant and non-dormant seed lots All seed produced 2010 in west TX

  7. 2011 UA48 stands UA48, 2011 Ark. Variety Test, Keiser UA48, 2011 Ark. Variety Test, Keiser UA48, 2011 Manila production field UA48, 2011 Manila production field

  8. Yields (lb/a) of UA48 in Arkansas Arkansas Strain Tests *2011 seedcotton yield at Keiser with Ark produced seed: DP393 = 2522, UA48 = 2802 Arkansas Cotton Variety Test

  9. Yields of UA48 in 2011 Production Fields, Planted using 2010 TX grown seed (Hearsay yields)

  10. 2011 Verification Field of UA48 in Phillips County Yield = 600+ lb/a Suspected glyphosate drift

  11. Performance of UA103 4 locations and 4 years (2005-08) of Strain Tests in Ark. (UA 103, patent pending) UA103 is a smooth leaf, very early maturing okra-leaf variety. Best yields at Judd Hill and Rohwer, AR and in south TX.

  12. Performance of UA222 4 locations and 4 years (2008-10) of Strain Tests in Ark. (UA 222, patent pending) UA222 is a moderately hairy leaf, early maturing variety. Appears to be very widely adapted.
