Description	The Fiber GP is a complex population developed from 24 parents with average to high fiber strength and short, medium, or long fiber length that flower during the summer at College Station, TX. Parentage included 19 high strength lines and five average strength lines. Nine lines had long fibers, five lines had medium length fibers, and ten lines had short fibers. This population had high variability in upper half mean fiber length (25.71 mm; range = 21.59-30.48 mm) and elongation (6.76%; range = 5.3-8.2%) but a narrow range of variability for fiber strength (310.47 kN m kg-1; range = 223.59-380.50 kN m kg-1), seed index (10.61 g; range = 7.92-13.60 g), and lint yield (502 kg ha-1; range = 232-834 kg ha-1). Micronaire averaged 4.38 units (range = 2.6-5.9 units), lint index averaged 5.15 g (range = 3.42-7.49 g), and boll size averaged 3.81 g (range = 2.05-5.81 g). The distribution of individual plant values for lint yield, boll size, lint index, and seed index in the Fiber GP was non-normal, providing evidence that selection for these traits could be effective. Positive correlations were observed between fiber strength and micronaire (r = 0.320), seed index (r = 0.372), and boll size (r = 0.244). No correlation was detected between lint yield and fiber strength or fiber length. Fiber length was positively correlated with seed index (r = 0.477) and negatively correlated with micronaire (r = -0.438). Elongation was positively correlated with lint index (r = 0.371), boll size (r = 0.471), lint yield (r = 0.513), micronaire (r = 0.631), and fiber strength (r = 0.501) but negatively correlated with upper half mean fiber length (r = -0.330).

Pedigree	24 parents were hybridized: PIs 165244, 154088, 154096, 158562, 153966, 529808, 529809, 529810, 529811, 529814, 529815, 163654, 163742, 163693, 154050, 154052; PD4461(Q); PD3364; Hybrid330 (line F); PD924; B1663-1; Acala1028; B1627-1; H2140-1. In the F3, pollen was collected and bulked for crossing. A male-sterile was introduced in the F4--100 bolls were harvested, seeds were bulked, and a sample was planted; no artificial selection was applied. The Fiber GP was random mated for nine cycles.
