Evaluation of Salt Tolerance and Genome-Wide Association Study in 249 Peanut Accessions (Arachis hypogaea L.)

Peanut (Arachis hypogaea L.) is considered as a moderately sensitive species to salinity stress, a few reports on salinity tolerance in peanut have been reported. The effects of different salinity concentrations on radicle length can be used to show the salinity effect on seed germination percentage and germination index. The present study was conducted 1) to determine the optimal NaCl concentration to test salinity tolerance at the germination stage, 2) to evaluate salinity tolerance of 249 peanut accessions, and 3) to identify genomic regions related to salinity tolerance by GWAS analysis.
