Interpretive Summary: Seven upland cotton germplasm lines were developed by the USDA-ARS and jointly released with Cotton Incorporated in 2017. The primary purpose for the release of these lines is to provide an alternative germplasm choice with superior fiber performance e.g., fiber strength, length, and uniformity under a range of irrigation levels combined with good yields to cotton breeders. In 2016, seven lines of the 27 advanced breeding lines (PSLC-U01, PSLC-U02, PSLC-U03, PSLC-U04, PSLC-U05, PSLC-U06, and PSLC-U07) were selected for release on the basis of good overall agronomic performance and superior fiber quality properties in these tests when they were compared to original parents and four Upland commercial check cultivars. For public and private breeders, PSLC-U01-U07 germplasm lines are an additional source for improving fiber quality of High Plains’ cotton.

Technical Abstract: Seven upland (Gossypium hirsutum L.) cotton germplasm lines— PSLC-U01 (Reg. No. ), PSLC-U02 (Reg. No. ), PSLC-U03 (Reg. No.), PSLC-U04 (Reg. No.), PSLC-U05 (Reg. No. ), PSLC-U06 (Reg. No. ), and PSLC-U07 (Reg. No. ) were developed by the USDA-ARS and jointly released with Cotton Incorporated in 2017. The primary purpose for the release of these lines is to provide an alternative germplasm choice with superior fiber performance e.g., fiber strength, length, and uniformity under a range of irrigation levels combined with good yields to cotton breeders. The PSLC germplasm lines originated from the cross of two distinct commercial cultivars from different cotton growing regions of the U.S., ‘Phytogen 72’ [PHY 72 (female) far west] and ‘Stoneville 474’ [STV 474 (male) mid-south]. The PSLC_U01-U07 lines were original selected from a total of 137 F7 recombinant inbred lines in 2014; each line derived from a single seed decent (F1 to F7). In 2014 and 2016, at USDA-ARS, Plant Stress and Germplasm Development Research Unit, Lubbock, Texas, l37 and 27 lines were evaluated in a randomized complete block design with three and four single 6.1 meter-plot replications under two irrigation regimes (regular and reduced ½ using surface drip irrigation system), respectively. In 2016, seven lines of the 27 advanced breeding lines (PSLC-U01, PSLC-U02, PSLC-U03, PSLC-U04, PSLC-U05, PSLC-U06, and PSLC-U07) were selected for release on the basis of good overall agronomic performance and superior fiber quality properties in these tests when they were compared to original parents and four Upland commercial check cultivars. For public and private breeders, PSLC-U01-U07 germplasm lines are an additional source for improving fiber quality of High Plains’ cotton.
