Interpretive Summary: Fusarium wilt (FOV4), a soil-borne fungal disease in cotton, devasted cotton production in California during the past decades. Recently, this pathogen was identified southeastern New Mexico and southwestern Texas and poses a threat to cotton production in these regions, as well as production on the High Plains of Texas, the largest Upland cotton producing region in the US. Historically, in regions where FOV4 persists, planting resistant Pima cotton varieties has been an effective and economical approach for dealing with this disease threat. Unfortunately, there are no commercial Upland varieties resistant to FOV4 in the US, to date. In this study, USDA-ARS and university cooperators released 17 Upland cotton lines (PSSJ-FRU01 – PSSJ-FRU17) with improved resistance to FOV4 and good fiber quality. The PSSJ-FRU01 – FRU17 line-series originated from crosses with parental lines known to possess moderate levels of FOV4 resistance. The lines were developed from six diverse cross-combinations using 10 parental lines with different genetic backgrounds. These lines showed improved resistance to FOV4 in both greenhouse and field trials. Further, these lines also showed good yield and comparable fiber quality in FOV4-infested fields compared to commercial varieties. The primary purpose for the release of the Upland PSSJ series is to provide cotton breeders with urgently needed sources for FOV4 resistance in Upland cotton. This is the first public Upland germplasm release derived from multiple cross-combinations, thereby increasing genetic diversity. All these lines will help to reduce the vulnerability of Upland cotton to this fungal pathogen and to advance efforts to broaden the genetic base which is critical to the Upland cotton industry.

Technical Abstract: With Fusarium wilt [Fusarium oxysporum f. sp. vasinfectum (FOV) W.C. Snyder & H.N. Hansen] race 4 (FOV4) formally identified in 2019 in New Mexico and in 2017 in El Paso, TX region in proximity to the High Plains of west Texas - the largest Upland (Gossypium hirsutum L.) cotton producing region in the US, the need to expand the genetic base of Upland cotton and develop cultivars resistant to FOV4 has become urgent. FOV4, a soil borne fungus, has impacted the cotton crop in the San Joaquin Valley (SJV) of California during the last 18 years. The primary purpose for the release of the Upland PSSJ series (FRU01 – FRU17) is to provide cotton breeders with urgently needed sources for FOV4 resistance in Upland cotton. The Upland germplasm lines were derived from six diverse cross-combinations using 10 parental lines with different genetic backgrounds e.g., DES 920 - PI 536522, NM12Y1004 (NuMex COT 15 GLS - PI 678371), MARS ROSE CLUSTER – PI 528483, AUBURN M PI 529214, and SA-3208 (LIAO MIAN 7 HAO). Recurrent selection was applied based on a single plant selection under greenhouse inoculations with FOV4 and infested field screenings from F1 to F4. In subsequent field and greenhouse tests, the lines showed improved resistance to FOV4 and fiber quality when compared to commercial cultivars. All these lines will help to reduce the vulnerability of Upland cotton to this fungal pathogen and to advance efforts to broaden the genetic base which is critical to the Upland cotton industry.
