Two Upland cotton (Gossypium hirsutum L.) germplasm lines, LA1110017 and LA1110004 were released by the LSU AgCenter due to their favorable combination of high fiber quality and yield. Both lines were developed by pedigree selection from a cross of ‘Paymaster 1560' and ‘FiberMax 832'. LA1110017 has a normal leaf shape, hairy leaves and pubescent stems. LA1110004 has smooth okra shaped leaves and pubescent stems. In performance trials averaged over 2003-2005, LA1110017 produced fiber with an average length of 1.19 inches and an HVI fiber bundle strength of 34.7 g/tex. LA1110004, evaluated during the same time period, produced fiber with an average length of 1.16 inches and a strength of 35.7 g/tex. Both have excellent fiber length uniformity. Lint yields of both lines were not significantly different from popular conventional cotton varieties. The combination of high fiber quality and yield potential in both of these lines will make them of value to plant breeders interested in developing cultivars of Upland cotton.
