Technical Abstract: To meet modern textile mill requirements and producer demands cotton, Gossypium hirsutum L., fiber quality must be improved. Genetic sources for fiber quality improvement must be identified and enhanced. Primitive race accessions offer sources to improve fiber quality. The utilization of race accessions has been limited because of their photoperiodic response. Fourteen lines derived from photoperiodic primitive race accessions have been converted to day-neutrality and selected for improved fiber strength. When evaluated in field trials the 14 germplasm lines generally had lower yield and lint percent compared to standard cultivars. The fiber length was almost equal to the cultivars; however, fiber strength was about 20% greater than that of check cultivars. These lines represent diverse day-neutral germplasm with improved fiber strength that is readily useable in cotton breeding programs.
