Technical Abstract: CLCuV (Cotton Leaf Curl Virus) is a major threat to cotton production in Pakistan and parts of India and has been reported in cotton producing countries in Africa, as well as China and Uzbekistan. Identifying sources of resistance to CLCuV helps not only countries such as Pakistan where the virus is already a problem, but also makes resistant germplasm widely available should CLCuV become a threat to cotton production in other countries. An ongoing project funded by USAID and USDA to identify sources of resistance to CLCuV was conceived and made possible with the resources available through the USDA National Cotton Germplasm Collection. The availability of this collection, combined with winter nursery seed increase capabilities, GRIN database information, and especially the recent addition of standardized descriptor data and digital images, made possible a rapid, coordinated CLCuV screening program. The results of the project and current status of the resistant sources identified will be reported.
