Iron-deficiency chlorosis in soybean is a persistent problem on calcare-ous soils of the upper Midwest. Substantial genetic variability for tolerance to iron-deficiency chlorosis has been found among popular varieties and in the germplasm collection. Due to significant breeding efforts, high-yielding varieties that are tolerant to iron-deficiency chlorosis are now available.
