A multidisciplinary research effort will use genetics and management to improve yield, fiber quality, and production stability in cotton. In objective 1, we will field evaluate an underutilized collection of cotton accessions grown under naturally occurring water deficit stress. We will relate the performance of these accessions to aquaporin and other water deficit stress sensitive candidate genes. In objective 2, contemporary plant breeding methods will be used to develop and release broadly adapted, high yielding germplasm lines with improved fiber quality. Also in objective 2, we will conduct water management studies to provide strategies that optimize cotton yield and fiber properties. Both of these objectives focus on increasing the profitability of the U.S. cotton crop. This research will identify candidate genes as novel breeding targets. It will develop germplasm as improved breeding stock. This research will also specifically provide irrigation recommendations when using site-specific center pivot and linear irrigation systems on fields that contain soils with different abilities to hold water. Industry customers will use these genetic and management products to help the nation’s cotton producers face increasing environmental and economic challenges.
