Screening Germplasm and Breeding for Resistance to Phomopsis Seed Decay of Soybean: Phase II Research
Soybean/maize Germplasm, Pathology, and Genetics Research
Project Number: 3611-22000-021-15
Start Date: Apr 01, 2012
End Date: Jun 30, 2014
1) Develop breeding/mapping populations and select high-yielding resistant breeding lines from the new sources of resistance identified in the first phase of this project; 2) Determine the genetics of resistance of these new sources of resistance and develop molecular markers for these traits; 3) Determine pathogen diversity, with emphasis on how this affects the expression of resistance to PSD in soybean.
Field screening and laboratory assays will be conducted to determine: 1) The resistance of soybean lines to PSD; and 2) The genetic and pathogenic diversity of PSD isolates collected and purified from different genotypes of soybean in different geographic origins.
