Info

Sunflower • All key components (saturated map, trait-marker association, fine mapped loci, mapped QTLs) for MAS available • Well saturated reference map developed with anonymous, gene-targeted and perfect markers available • A well characterized wild species’ gene-pool for introgression available - already SNPs and their LD decay for wild populations available • Well characterized resistance gene islands for introgression • TILLING platform available • Time and resources ripe for exploitation of MAS in crop improvement SND, Alternaria, downey mildew and powdery mildew tolerance – immediate task
