Abstract

AbstractPD 20170048 (Reg. no. GP‐1092, PI 698606), PD 20170049 (Reg. no. GP‐1093, PI 698607), PD 20170050 (Reg. no. GP‐1094, PI 698608), PD 20170053 (Reg. no GP‐1095, PI 698609), and PD 20170054 (Reg. no. GP‐1096, PI 698610) are noncommercial breeding lines of upland cotton (Gossypium hirsutum L.) jointly released by the USDA–ARS, the Clemson University Experiment Station, and Cotton Incorporated in 2020. PD 20170048, PD 20170049, PD 20170050, PD 20170053, and PD 20170054 are breeding lines selected from a cross between an elite cultivar or germplasm line and an exotic landrace accession from Asia, Africa, or South America. Each breeding line possesses 50% exotic landrace parentage, excellent fiber quality, and excellent yield performance—significantly better than several commercial cultivars. PD 20170048, PD 20170049, PD 20170050, PD 20170053, and PD 20170054 display good adaptation in three distinct regions of the U.S. upland cotton production region and provide valuable sources of new genetic diversity to cultivar development programs.
