| 0 | PI 699963 | 'PSSJ-FRP01' | Gossypium barbadense L. | Texas, United States | COT | | Not Available | 2022 | DEVELOPED | | | | | | Breeding material | Pima PSSJ-FRP01, PSSJ-FRP02, and PSSJ-FRP03 lines possess improved resistance to Fusarium wilt [Fusarium oxysporum f. sp. vasinfectum (FOV) Atk. Sny & Hans], FOV race 4 (FOV4). Pima S-6 possesses a major gene(s) for FOV race 4 resistance. SA-3208 also contained plants moderately resistant to FOV4. PSSJ-FRP01 was developed, advanced, and maintained as a mixed population, and breeding pedigree of this line before the ID designation of PS-592 (2012) is obscure. Mass selection was applied toward selection of columnar growth and fruiting cluster habit genotypes, and open pollinated bolls were harvested from single plants in 2007. On the other hand, the breeding of PSSJ-FRP02 and PSSJ-FRP03 Pima germplasm lines started in 2014-2015. Field and greenhouse plant FOV4 response to infection by inoculum pressure was assessed through evaluations of foliar symptoms (FS), vascular root staining (VRS) and percent survival (PS), and measures of relative plant vigor. Recurrent cycles of selection was applied based on a single plant under FOV4 infested field screening from F1 to F4. In 2019-2020 germplasm lines had a VRS value of less than 1.0 (VRS scale 0 to 5 - dead) and PS higher than 91.0 %, during infested field evaluations in the San Joaquin Valley (SJV) of California and in the El Paso, TX with significant differences (p < 0.05) between the susceptible cultivar-checks Pima S7 and Pima 3-79. Preliminary analyses of fiber quality traits for the germplasm lines collected in 2020 in Five Points, CA revealed good to superior fiber quality compared to standard fiber quality-ranges of Pima commercial cultivars. The primary purpose for the release of the Pima is to provide to the cotton breeders urgently- needed sources for continuing to improve FOV race 4 (FOV4) resistance in Pima cotton, reduce the vulnerability of the Pima cotton industry to this fungal pathogen, and advance efforts to broaden the genetic base which is critical to the future of the Pima cotton industry in the US | 2137123 | PI 699963 |
