Abstract
A method for introgressing soybean cyst nematode resistance into elite soybean germplasm is disclosed. The method involves using genetically mapped loci associated with soybean cyst nematode resistance for marker-assisted selection during introgression of soybean cyst nematode resistance into elite soybean germplasm. Also disclosed are a method for confirming selection for soybean cyst nematode resistance; quantitative trait loci associated with soybean cyst nematode resistance; and soybean lines bred to be resistant to soybean cyst nematode infestation.
Claims10
A method of reliably and predictably introgressing soybean cyst nematode resistance into non-resistant soybean germplasm comprising using one or more nucleic acid markers for marker assisted selection among soybean lines to be used in a soybean breeding program, wherein the nucleic acid markers are pA85a, php02302a, php02340a, pk400a, pt155a, pBLT24a, php05180a, pSAC3a, pA11116, php02366a, php02361a, UBC440a, pk69a, pL50b, pA226a, pA715a, pk24a, pB157b, php02275a, UBC379a, OPC-04a, or php02301a;
- further comprising introgressing said resistance into said non-resistant soybean germplasm.
A quantitative trait locus associated with resistance to soybean cyst nematode race-3, said locus mapping to soybean linkage group A, and mapped by one or more of markers pA85a, php02302a, php02340a, pk400a, pT155a, pBLT24b, php05180a, pSAC3a, and pA111b.
A quantitative trait locus associated with resistance to soybean cyst nematode race-3, said locus mapping to soybean linkage group G, and mapped by one or more of markers php02366a, php02361a, UBC440a, pk69a, UBC576a, and pL50b.
A quantitative trait locus associated with resistance to soybean cyst nematode race-3, said locus mapping to soybean linkage group M, and mapped by one or more of markers pA226a, pA715a, pk24a, pB157b, php02275a, UBC379a, OPC-04a, and php02301a.
