Technical Abstract: Fiber yield and qualities are two most important goals of cotton breeding programs worldwide. The modern DNA marker technologies are proven to be useful in tagging candidate genes for trait of interest and therefore, are greatly accelerating the breeding programs to develop well-adapted cotton varieties with superior fiber quality. However, the narrow genetic base of currently available cotton cultivars makes it difficult to map agronomically important traits using molecular markers; therefore, there is a need to explore novel germplasm resources and identify candidate genetic resources for important agronomic traits including fiber quality and yield. As a collaborative research program between USDA-ARS and Uzbekistan, a number of wild G. hirsutum races (ssp.palmeri, ssp.richmondi, ssp. morilli, ssp. mexicanum, ssp.latifolium, ssp. malum, ssp.yucatanense, ssp. punctatum, ssp. purpurascens etc.) and G. hirsutum accessions belonging to ssp. euhirsutum (according to Mauer) that represent a wide range of ecological niche.
