TAM 94L-25 was developed at the Cotton Improvement Lab of Texas A&M University and released as an improved germplasm line in 2002. This germplasm release was based on its fiber quality package combined with a compact boll shape and competitive yield potential. This line averages 1.2 UHM fiber length and 30 g/tex fiber bundle strength. TAM 94L-25 resulted from a complex pedigree that included PD, Stoneville, Deltapine, Lankart, Acala, Fox, Gregg, and Tideland. The PD parent as well as others in the complex pedigree may have alleles contributed by G. barbadense. TAM 94L-25 was subsequently used as a parent and resulted in the selection of upland genotypes with Extra Long Staple phenotypes. These lines range to 1.40 UHM length and 35.4 g/tex fiber bundle strength in 2005 at College Station, Texas.
