The single seed descent (SSD) method of inbreeding minimizes the amount of genetic sampling. The single-pod descent (SPD) and bulk methods (BM) produce redundant inbred lines that are descended from either the same F2 or F3 plant. However, for soybean [Glycine max (L.) Merr.], the SSD method requires more time to process the seed than the SPD or BM. Our(More)
Iron-deficiency chlorosis (IDC) is an important agronomic trait when soybean (Glycine max (L.) Merr.) is planted on calcareous soil. Breeders need confirmation that marker-QTL (quantitative trait loci) associations developed using association mapping, will be effective in a different set of genotypes than the ones used to identify those markers.
