Interpretive Summary: Cotton breeders continue to need alternative sources of cotton breeding lines for improving Fusarium wilt (FOV race 4) resistance in Pima cotton in California. FOV race 4 is a fungus that has impacted cotton yields in the San Joaquin Valley (SJV) for the last 12 years. For this purpose, the Agricultural Research Service, United States Department of Agriculture and University of California announce the release of five Pima cotton germplasm lines, Pima SJ-FR05, Pima SJ-FR06, Pima SJ-FR07, Pima SJ-FR08, and Pima SJ-FR09, that possess good resistance to FOV race 4, and good lint yield and fiber quality characteristics such as fiber fineness, length, and strength. Pima SJ-FR05-FR09 series originated from the cross of germplasm lines, Pima S-6 and 89590. Pima-S6 possesses a major gene(s) for FOV race 4 resistance. The SJ-FR05-FR09 lines showed good resistance to FOV race 4, compared to the resistant and susceptible checks, and parental lines. In addition, field experimental data revealed that the Pima SJ-FR05-FR09 series showed good fiber quality traits (length, strength, and fineness) when compared to the (SJV Pima cotton standard of California. The SJ-FR05-FR09 series will help to speed efforts to broaden the genetic base, which is critical to the success and future of the Pima cotton industry.
