Research Project: NATIONAL COTTON VARIETY TEST PROGRAM

Location: Crop Genetics Research Unit

Project Number: 6402-21000-032-00
Project Type: Appropriated

Start Date: May 14, 2008
End Date: Apr 17, 2013

Objective:
Objective 1: Organize, collect data, analyze, and report the NCVT. Objective 2: Estimate variety (V), environmental (E), and their interaction components (VE) and relate results to improved breeding and evaluation of varieties for specific environments. Objective 3: Measure the genetic progress in yield, yield components, and fiber traits. Objective 4: Evaluate variety, environmental, and their variety x environmental contributions of fiber and seed traits that are not usually evaluated in variety tests.

Approach:
Organize and design annual tests, assemble data, analyze, publish and communicate results to cooperators and the public. Archive and make database available to cooperators. Reinforce ARS genetic fiber quality studies. Perform or assist in special variety, years, and location analyses. Update variety evaluations by using the latest technology improvements in computer and statistical services and fiber quality instrumentation. Use NCVT database to detect long term and regional trends in yield and seed and fiber quality. Explore the use of molecular markers (RFLPs) to fingerprint varieties and genetic populations. Utilize database to associate environmental effects on cotton. Utilize residual fiber samples to correlate data from new instrumentation with database. Utilize seed and fiber samples from the NCVT to measure the genetic, environmental, and their interactions on new traits.
