Abstract

TAM 04WB-33s upland cotton (Gossypium hirsutum L.) germplasm line (Reg. No. GP-940, PI 662041) was developed by the Cotton Improvement Laboratory, Department of Soil and Crop Sciences, Texas A&M AgriLife Research and released in 2010 as part of an ongoing effort to create germplasm with combinations of improved fiber-quality parameters, especially upper half mean length (UHML) and fiber bundle strength (FBS), that contribute to the production of improved yarn. TAM 04WB-33s exhibited high volume instrument (HVI) UHML and FBS greater than the comparison cultivars when grown under irrigated culture at multiple locations in central and south Texas during 2007, 2008, and 2009. Limited yarn evaluation indicated that TAM 04WB-33s produced 30-count carded yarn that was 27% stronger and required 43% more force to break than either ‘DP 491’ or ‘FiberMax 832’. This germplasm line is competitive in all other fiber properties and in yield potential with current upland cotton cultivars adapted to central and south Texas.
