Quantitative trait loci associated with soybean cyst nematode resistance and methods of their use

摘要

Several QTLs that are genetically linked to resistance to soybean cyst nematode (SCN) are disclosed. These QTLs have been mapped to genomic regions on Chrs. 4, 8, 10, 11, 18, and 20 of soybean, G. max. Candidate genes underlying these QTLs as defined by the flanking markers, as well as genetic markers associated with these QTLs are also disclosed. These markers can be utilized for introgressing SCN resistance into non-resistant soybean germplasm. The unique resistance genes can be introduced into a non-resistant plant by marker-assisted selection (MAS) or by transgenic methods.
