Interpretive Summary: PD 98066 and PD 99035 are noncommercial breeding lines of cotton jointly released by the Agricultural Research Service, United States Department of Agriculture, the Clemson University Experiment Station, and Cotton Incorporated in 2007. PD 98066 and PD 99035 possess outstanding fiber strength and length potential, while also maintaining micronaire values lower than commercial cultivars. Both germplasm lines possess mid- to late-maturity and produce lint yields similar to or just below commercial cultivars. PD 98066 and PD 99035 are best adapted and competitive with commercial cultivars within the southeastern USA. However, our data also suggest that PD 98066 and PD 99035 have broad adaptation across the USA Upland cotton production region that warrants their use in regions other than the southeastern USA. The combination of longer fiber length, stronger fiber strength, lower micronaire, and acceptable lint yield potential make PD 98066 and PD 99035 valuable genetic resources to cotton breeding programs.

Technical Abstract: PD 98066 and PD 99035 are noncommercial breeding lines of cotton (Gossypium hirsutum L.) jointly released by the Agricultural Research Service, United States Department of Agriculture, the Clemson University Experiment Station, and Cotton Incorporated in 2007. PD 98066 was selected from a cross of PD 5363 and GA 88-186, and PD 99035 from a cross of PD 93043 and ‘DPL 5409’. PD 98066 and PD 99035 both possess outstanding fiber quality properties significantly better than several commercial cultivars. Specifically, PD 98066 and PD 99035 possess outstanding fiber strength and length potential, while also maintaining micronaire values lower than commercial cultivars. Both germplasm lines possess mid- to late-maturity and produce lint yields similar to or just below commercial cultivars. PD 98066 and PD 99035 are best adapted and competitive with commercial cultivars within the southeastern USA. However, our data also suggest that PD 98066 and PD 99035 have broad adaptation across the USA Upland cotton production region that warrants their use in regions other than the southeastern USA. The combination of longer fiber length, stronger fiber strength, lower micronaire, and acceptable lint yield potential make PD 98066 and PD 99035 valuable genetic resources to cotton breeding programs.
