2003 Low Desert Upland Cotton Advanced Strains Testing Program

Abstract

Upland cotton advanced strains and commercial check varieties were evaluated in replicated field studies at three locations in 2003. The test sites include Safford, AZ, Maricopa, AZ, and Yuma, AZ. Seven seed companies submitted a maximum of ten advanced strains entries per location. Three commercial check varieties were used at the Safford and Yuma sites, and included ST4892BR, DP449BR, and DP565. Two commercial check varieties were used at the Maricopa site and included ST4892BR and DP449BR. Data collected included vigor and relative maturity ratings, yield, and fiber quality. The research is conducted in order to develop public unbiased performance data of genetic materials that have moved to the advanced stages of testing and are being considered for commercial release. The data has historically been used to add to seed company databases and assist with commercial release decisions.
