Most public programs lack the resources to undertake a geographically diverse evaluation of their elite breeding lines. The Regional Breeder Testing Network (RBTN) provides multi-location testing, with established protocols, to assist public cotton breeders in their efforts to develop improved germplasm. An additional benefit is the exchange of elite non-transgenic germplasm between programs for use in developing new populations that address future cotton quality and agronomic needs and broadens the genetic base available for improvement efforts. Online access ( of performance data provides for citation of germplasm performance in crop registration and reporting. Access to multi-year RBTN data also allows for development and use of tools/software to aid breeders in germplasm development. In addition to yield and fiber evaluation, trials included evaluations for verticillium wilt, nematodes, tarnished plant bug, and heliothis. The RBTN provides a wealth of information that otherwise would be impractical for an individual breeder to obtain. Publicly developed germplasm can widen the gene pool available for development of cultivars that will be competitive in the international market. The breeding component of this project will also allow for exploration and development of additional tools such as the RBTN to exploit coordinated efforts of public breeding programs that operate within very limited resources.
