Variety selection is the most important management practice for producers with chlorosis-prone soils. No soybean variety is immune to chlorosis, but large differences occur between the most tolerant and most susceptible varieties.
With checkoff funding provided by the NCSRP, a group of soybean geneticists and plant breeders from four states have identified the genomic regions in soybean associated with IDC tolerance. With this new understanding, they have been able to develop new, highly accurate genetic markers that breeders are now using to select for IDC-tolerant varieties.
