Research Project: Developing Drought Tolerant Soybeans Using Extreme Phenotypes

Location: Crop Genetics Research

Project Number: 6066-21220-012-07-R
Project Type: Reimbursable Cooperative Agreement

Start Date: Apr 1, 2011
End Date: Dec 31, 2013

The objective of this project is to couple molecular genetics and physiology such that we can identify drought tolerant parental genotypes and those genotypes that have an increased likelihood of having unique drought tolerant alleles.

The approach of this research is to 1) examine the extreme phenotypes in greater physiological detail under control and managed drought conditions, 2) compare the responses of the extreme genotypes to other measures of drought tolerance, 3) develop populations segregating for CID and NDFA (including developing RIL) based on genotypic and physiological criteria, 4) phenotype segregating populations, 5) initiate a mapping program to identify genes associated with CID and NDFA, and 6) integrating global transcriptome analyses with physiological characterization and molecular marker development.
