APSA-WorldVeg Loofah Project

A special project entitled “Creating Sustainable Markets with Solid Loofah Genetics: WorldVeg's leaf curl virus and downy mildew disease-resistant lines of different market segments essential to develop breakthrough hybrids” is launched under the APSA-WorldVeg Vegetable Breeding Consortium with the following four deliverables:

  1. 200 new elite lines of ridge and sponge gourds of different market segments with resistance to Tomato leaf curl New Delhi virus (ToLCNDV) and downy mildew; 4-5 white seeded diversified genetic background sponge gourd lines.
  2. 40-50 WorldVeg’s experimental F1 hybrids demonstrated at field day each year for observation and selection.
  3. Information of the genetic diversity of WorldVeg ridge and sponge gourd lines and commercial checks based on Single Nucleotide Polymorphism (SNP) marker analysis.
  4. SNP markers associated with QTLs conferring resistance to ToLCNDV in ridge gourd provided for marker-assisted selection.
