Breeding for Chilli Leaf Curl Disease (ChiLVD) and South East Asian Thrips (Thrips parvispinus) resistance in Chilli Regsitration Period: May - 15 July 2024

APSA is pleased to announce that registration is now open for a 3-year collaborative project title “Breeding for Chilli Leaf Curl Disease (ChiLVD) and South East Asian Thrips (Thrips parvispinus) resistance in Chilli” with ICAR- Indian Institute of Horticultural Research, Bangalore. 

SUB-PROJECT I: Breeding for Chilli Leaf Curl Disease (ChiLVD) resistance in Chilli


  1. Survey & identification of major begomoviruses and their recombinants prevalent in major chilli growing areas
  2. Screening pooled germplasm at selected hot spots to identify stable sources of resistance against major begomoviruses identified
  3. Development of RxS segregating populations to identify resistance loci against major begomoviruses
  4. Identification of QTLs, Meta-QTLs and candidate genes associated with resistance loci and development & validation of SNP based markers
  5. Pyramiding of resistance loci through MAS


  1. Stable resistant sources for multiple begamoviruses will be identified
  2. Better understanding of Genotype x Pathogen x Environment on resistance of ChLCD
  3. QTLs associated with multiple begamoviruses will be identified
  4. Meta QTLs (if any) conferring resistance against multiple begamoviruses
  5. SNP marker assays associated with multiple begamoviruses resistance
  6. Advanced stable resistant lines (with pooled resistant loci) will be developed

SUB-PROJECT II: Breeding for South East Asian Thrips (Thrips parvispinus) resistance in Chilli


  1. Screening chilli accessions for thrips resistance
  2. Metabolite profiling of selected chilli accessions
  3. Identification of rQTLs (resistant QTLs) and mQTLs (metabolite QTLs) in chilli conferring resistance against thrips 
  4. Incorporation of resistance loci into desirable background through MAS


  1. Resistant accessions against south east Asian thrips
  2. Understanding of mechanism of south east Asian thrips resistance
  3. Genetic mechanism of south east Asian thrips resistance
  4. QTLs conferring resistance and associated markers for MAS
  5. Advanced breeding lines with thrips resistance


210,000 USD. The participating companies will share equal funds to the project (for example if 10 APSA member companies join this project, each company will pay 21,000 USD over 3 years (USD 7000/ year approximately) to participate in the project.

**The participating companies shall be Indian companies or multinational companies having subsidiary in India to get utmost benefits of the project since the germplasm cannot be shipped outside of India.**

May – July 15, 2024 Regsitration Period
July 15, 2024 at 11.59 pm (ICT) The Registration is Closed
July 2024 Confirmation of additional participants 
September 2024 Expected project commencement
