Location: Soybean and Nitrogen Fixation Research
Project Number: 6070-21220-069-120-A
Project Type: Cooperative Agreement
Start Date: Oct 1, 2021
End Date: Sep 30, 2022
Objective:
Develop drought-tolerant cultivars adapted to locations in Missouri and other
drought-prone U.S. environments that will aid farmers with variety choices and
guide new public-private breeding efforts to fix the drought problem.
Approach:
GWAS will be performed to identify candidate genes associated with slow wilting trait in the diverse set (~440 lines) with whole genome resequencing data in 2022. Conduct GWAS to identify candidate genes associated with root trait in the diverse set (~500 lines) with whole genome resequencing data in 2022. The abundant genomic information of these lines will facilitate us to identify candidate genes regulating slow wilting and drought tolerance. QTL mapping will also be conducted in a recombinant inbred population (S05-11482 x PI 458515) to identify slow wilting genes for the drought tolerant parent PI 458515. The discovery of those candidate genes will lead to understanding of drought tolerance mechanisms and design genomic assisted breeding strategy.
