Location: Crop Genetics Research
Project Number: 6066-21000-053-008-S
Project Type: Non-Assistance Cooperative Agreement
Start Date: Aug 1, 2024
End Date: Jul 31, 2026
Objective:
To evaluate differences in cotton fiber types at initiation and determine the underlying basis for those differences. This will include creation of cotton populations derived from crosses between plants with unique fiber types, microscopic imaging and analysis of the developing fiber types in progeny, and identification of the genomic location of the fiber trait and associated genetic markers.
Approach:
ARS and the Cooperator will cooperatively:
1. Collect samples from field plots in Mississippi or from sites in North Carolina and analyze for them fiber type.
2. Collect mature fiber samples and analyze them for fiber quality.
3. Make crosses and generate F2 progeny to determine the genomic location of the fiber type trait.
4. Identify DNA markers associated with the fiber type trait.
