Patent ID: 7919675

Claim:
A method for selecting a disease-resistant soybean plant, the method comprising: a) detecting a marker nucleic acid, wherein the marker nucleic acid maps ten centimorgans or less from a disease-resistance gene allele, wherein the marker comprises a nucleotide sequence corresponding to an expressed gene sequence, wherein the marker is selected from the group consisting of (i) a polynucleotide sequence that is at least 90% identical to SEQ ID NO: 1 (SSLP039), and (ii) a polynucleotide sequence completely complementary to the nucleotide sequence of (i), and wherein the disease-resistance gene allele is selected from the group of resistance alleles consisting of frogeye leaf spot resistance gene (Rcs3), brown stem rot resistance gene 1 (Rbs1), brown stem rot resistance gene 2 (Rbs2) and brown stem rot resistance gene 3 (Rbs3); and, b) selecting a plant comprising the marker nucleic acid, thereby selecting a disease-resistant plant.
