2019 SASHA Brief 03. Tackling virus resistance in hot spots.

Discriminated between resistant and tolerant cultivars in response to Sweet potato feathery mottle virus (SPFMV) and Sweetpotato chlorotic stunt virus (SPCSV). Dual infection by SPCSV and SPFMV cause sweetpotato virus disease (SPVD), that can cause devastating losses.
• Identified SPVD field resistant clones to be used as parents to breed (cross) for increased SPVD resistance in breeding populations
• Identified SPVD field resistant clones for forming a diversity panel for developing molecular markers
• Increased the frequency of SPVD resistant genotypes in breeding populations from less than 0.05% to over 20%.
