摘要： GA R01-40-08 (Reg. no. GP-1060, PI 690433), is a Gossypium hirsutum L. germplasm line developed by the Molecular Cotton Breeding Laboratory, Department of Crop and Soil Sciences, at the University of Georgia. GA R01-40-08 was selected from an interspecific backcross inbred population derived from the cross of 'Tamcot 2111' (G. hirsutum) with 'Pima S-6' (G. barbadense L.). This G. hirsutum germplasm line harbors an introgressed quantitative trait locus (QTL), qFL-Chr.1, conferring improved upper half mean fiber length (UHML) from Pima S-6. Field trials conducted in Plains and Tifton, GA, in 2009, 2013, and 2014 indicate that GA R01-40-08 exhibits improved UHML of 1.5 mm longer than the Tamcot 2111 parent, representing a 5% improvement. GA R01-40-08 had fiber yields over 18% higher than the Pima S-6 parent and equivalent to the higher-yielding parent, Tamcot 2111. This germplasm line represents a milestone in upland cotton germplasm improvement as the first publicly released germplasm line carrying a fiber length QTL with an effect that has been validated in multiple environments. It will provide upland cotton breeders with an adapted source of the qFL-Chr.1 QTL for improved UHML from G. barbadense, and the tightly linked markers published previously will allow breeders to use marker-assisted selection for rapid incorporation.
