This invention is the development of a better cotton seed. Genetically, this Upland Cotton Naked Tufted Mutant seed has been genetically enhanced, reducing the formation of linters on the seed coat (fuzz left on the seed after ginning). The incorporation of this mutant seed phenotype into a commercial variety of upland cotton (Gossypium hirsutum L.) reduces seed coat neps (waste from the seed plant ovules), reduces the short fiber content (changing the quality of cloth made from the cotton), and increases oil content of the ginned seed. In addition, this trait will reduce the energy and time required for ginning as well as reduce the need to acid delint cotton seed prior to planting.
Market Applications:
Reducing the need for acid delinting in upland cotton has widespread commercial potential in cotton crop management. Acid delinting will become outdated as the use of the Naked-Tufted Mutant will increase, causing more affordable and effective crop production techniques to be widely available.
Features, Benefits & Advantages:
· Reduces the cost of production.
· Increases seed oil content.
· Improves fiber quality of cotton grown.
· Occurs as incorporated into several, modern cultivars of cotton: cultivars that have higher yield potential and better fiber quality cotton.

Patent: PCT/US08/74137 - 12/197,296
Development Stage:
This is being incorporated into elite genotypes and additional tests are being conducted to fully characterize enhanced ginning efficiency. An extensive data base has been developed on field tests conducted in Lubbock, TX and fiber analyses conducted at the Texas Tech International Textile center.
