Improvement of Upland Cotton with Interspecific Introgression

In an effort to enhance allelic diversity in upland cotton, interspecific hybridization were made between Gossypium hirsutum and G. barbadense as well as converted G. tomentosum and G. mustelinum lines. Breeding lines are at all stages of development. Overcoming negative linkage drag for yield has been a considerable challenge. The most notable improvements have been made in fiber quality.
