  • Patent number: 6300541
    Abstract: The invention provides a method of introgressing soybean sudden death syndrome (SDS) or soybean cyst nematode (SCN) resistance into non-resistant soybean germplasm. Loci associated with SDS resistance or with SCN resistance in soybean lines known to be resistant to SDS or the SCN are used in marker assisted selection during introgression of SDS or SCN resistance into elite germplasm. In addition, the method may be used to confirm selection of resistance in new soybean cultivars.
