International genetic, cytogenetic and germplasm resources for cotton genomics and genetic improvement. In: Proceedings of International Cotton Advisory Committee World Cotton Research Conference, September 10-14, 2007, Lubbock, Texas.

Interpretive Summary: Improvement of cotton is increasingly reliant on diverse germplasm and genetic tools to facilitate introgression of valuable genes into cotton cultivars. This presentation summarizes the current state of knowledge of all known germplasm resources and technological advances used to research and selectively introduce genes into cotton. International cooperation in conservation and utilization of cotton germplasm was fostered with this presentation. Future directives to improve the breadth of the cotton germplasm collections and the utilization of molecular tools for cotton breeding were also discussed.

Technical Abstract: A general understanding of the nature, uses and need of cotton germplasm collections is important to maintaining support for them and their utilization. Such support is vital to addressing the future challenges and needs of cotton, which will be many and varied. The solutions to many of these challenges will be genetic and involve the scientific utilization of cotton genetic germplasm resources. In this presentation, we will look at a number of key sites from around the world to illustrate the types of genetic, cytogenetic and germplasm collections that exist. The taxa that constitute cotton germplasm can be categorized into primary, secondary and tertiary "gene pools" that progressively connote both the relative difficulty of introgression and their likelihood of harboring new genetic diversity. We will exemplify past and ongoing usage. Patters of introgression reflect the gene-pool classifications. The international Cotton Genome Initiative (ICGI) is facilitating globalization of scientific interactions that affect these collections, their access, and their contributions to cotton science and genetic improvement – these will benefit cotton worldwide. Lastly, we will look at what the near future may bring in the way of new paradigms for utilization of genetic stocks, cytogenetic stocks, germplasm and molecular markers in cotton science and genetic improvement.
