Abstract:
1. A method for identifying the presence or absence of a gene coding for resistance to Aphis glycines in soybean germplasm comprising: analyzing said germplasm by marker-assisted selection (MAS) to: detect a resistance to determine the presence or absence of an allelic form of DNA linked to the gene coding for resistance to wherein the presence or absence of said allelic form of DNA linked to said gene is determined by comparing a first PCR-amplified polymorphic marker fragment of said soybean germplasm to a second PCR-amplified polymorphic marker fragment of soybean germplasm from a plant having determining that said gene coding for RAG resistance is present in said soybean germplasm when said first fragment is substantially the same size as said second fragment, and determining that said gene is not present in said germplasm when said first fragment is not substantially the same size as said second fragment.
