The Arkansas Agricultural Experiment Station announces the release of two noncommercial breeding lines of cotton, Gossypium hirsutum L., designated as Arkot A129 and Arkot A132. Both lines were derived from crosses made in 1981 with one common parent, FTA266. The second parent of Arkot A129 and Arkot A132 was 'Cascot L7' and 'Stoneville 825', respectively. FTA266, which is the source of high fiber strength in these lines, was developed by a complex series of crosses described by Culp and Harrell (1975). The pedigree of FTA266 includes Triple Hybrid 108, Triple Hybrid 171, AHA 6-1-4, 'Earlistaple', and 'Sealand 542'.
