Abstract

‘UA48’ (Reg. No. CV-129, PI 660508) is a conventional cultivar of cotton (Gossypium hirsutum L.), that was released by the Arkansas Agricultural Experiment Station in November 2010. Parents of UA48 included Arkot 8712 and FM 966. UA48 was released as part of an ongoing effort to develop improved genotypes having enhanced yield, yield components, earliness, host-plant resistance, and fiber properties. In most tests, UA48 had a lint yield comparable to that of DP 393, a well-adapted conventional cultivar. It appears to be best adapted to silt loam soils in the northern areas of U.S. cotton production. UA48 matures as early as any cultivar that is adapted to the Mississippi River Delta. It displays high resistance to bacterial blight and is equal to DP 393 in its response to other diseases. Fiber quality of UA48 is exceptional. In most tests, its fiber length, length uniformity, and strength exceeded most, and frequently all, other entries. Its micronaire is comparable to DP 393. UA48 displays an unusual combination of high yield, early maturity, and high fiber quality.
