Knowledge of genetic relationships in crop breeding programs provides valuable information that can be used by plant breeders as a parental line selection tool. In Upland cotton (Gossypium hirsutum L.), the Pee Dee germplasm program represents one of the most historically signiWcant Upland cotton breeding programs and is known as a key source of Wber quality genes for commercial cultivars. The foundation of the Pee Dee germplasm is known to represent an array of genetic diversity involving the hybridization of G. hirsutum L., G. barbadense L., and triple hybrid strains (G. arboreum L. £ G. thurberi Todaro £ G. hirsutum L.). In this study, we characterized genetic relationships within the Pee Dee germplasm collection using molecular marker and Weld performance data. Molecular marker and Weld performance data showed the Pee Dee germplasm collection still maintains useful amounts of genetic diversity. The methods described provide plant breeders of cotton and other crops a strategy to develop a parental line selection tool based on genotypic and phenotypic information. Cotton breeders can directly use the information provided to select speciWc Pee Dee germplasm parental line combinations based on genotypic (molecular marker) and phenotypic (Weld performance) information rather than relying on pedigree and phenotypic information alone.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
