Soybean Sudden Death Syndrome Resistant Soybeans, Soybean Cyst Nematode Resistant Soybeans, and Methods of Breeding and Identifying Resistant Plants
Project Leader: David Lightfoot
Unit: College of Agricultural Sciences, Department of Plant, Soil, and General Agriculture
Brief Description:
This invention is a method of introgressing soybean sudden death syndrome (SDS) and Soybean Cyst Nematode (SCN) resistance into nonresident soybean germplasm. Loci associated with SDS resistance in soybean lines known to be SDS resistant are used in marker-assisted selection during introgression of SDS resistance into elite germplasm. Loci associated with SCN resistance in soybean lines known to be SDS resistant are used in marker-assisted selection during introgression of SCN resistance into elite germplasm. The method also confirms selection of resistance in new soybean cultivars.
Patent Status:
U.S. Patent No. 6,300,541, issued October 9, 2001. Additional patent pending.
Potential Commercial Uses:
This invention may substantially increase soybean disease resistance and, therefore, yields (via marker-assisted selection). The markers may also be used to clone the genes for resistance enabling their transfer among elite cultivars by transformation.
