4. DNA Markers in DUS – Gaining MomentumUPOV BMT Session# Abstracts
5. Modern Breeding Necessitates New Methods in DUS Breeding Methods: DNA markers, established heterotic pools, faster cycle timeBreeding Selection Criteria: Performance (yield, agronomics, disease)DUS Criteria: Morphology (non-performance visual observation)Standard morphological descriptors often fail to establish distinctness.PVP Office asks for additional evidence.Breeder returns to field -> time, $$.DNA markers can be used to establish distinctness.
6. Molecular Marker Working Group (MMWG)United States Plant Variety Protection Board American Seed Trade AssociationJoint Molecular Marker Working GroupPurpose: Explore methods for using DNA markers in DUS
7. MMWG Focus - Direct Varietal ComparisonsMarker similarity as supplemental evidence when standard morphological descriptor comparison is inconclusive for two varieties.Establish method and determine proper threshold for application of marker similarity.Scientifically vetted methods (peer review)Grounded in morphologySoybean first (greatest need)
8. UPOV BMT/16Four MMWG talksThe use of Reference Variety Similarities in Varietal Distinctness II: Reference Variety SelectionAssessment of reproducibility of 6K SNP genotyping in soybean across laboratoriesDetermining the parameters to characterize Soybean varieties using single nucleotide polymorphismsUpdate on the American Seed Trade Association and United States PVP Office Molecular Marker Working GroupMinimal negativity toward US approachAnti-DNA marker sentiment is fadingNetherlands: French Bean – encouraging test-case
9. Next StepsPrepare final recommendation for the PVP Office/BoardGlobal engagement:CPVO IMODDUS (EU marker working group)SAA marker working group – soy harmonizationBMT/17 September 2017Additional Crops/ModelsThank You
