Project Number: 3607-21000-012-04
Project Type: Reimbursable

Start Date: Oct 01, 2009
End Date: Sep 30, 2012

Objective:
We will conduct fine mapping of the Rag2, Rag3, Rag4 genes for soybean aphid resistance with SNP markers. Also identify candidate genes and proteins for the Rag2 gene identified earlier by ARS.

Approach:
To develop SNP markers for soybean aphid resistance genes for marker assisted breeding for Rag2, Rag3, and Rag4 genes: SNP markers will be identified in the genomic regions of the aphid resistance genes using appropriate RIL mapping populations (already in hand) and near isogenic lines. The Solexa sequencing and Illumina genotyping platforms will be used for this objective/strategy.
