Molecular Sex Determination

Project Brief on Molecular Sex Determination in Aquilaria malaccensis — highly relevant to improving breeding, propagation, and plantation planning under your initiatives like COPI (Crown Organogenesis Protocols Inc.) and allied ventures.


Project Brief: Molecular Sex Determination of Aquilaria malaccensis

Project Title

“Early Sex Identification in Aquilaria malaccensis via DNA Marker-Assisted Selection for Optimized Plantation and Breeding Programs”


Project Objective

To develop and apply a reliable molecular protocol for early sex determination in Aquilaria malaccensis seedlings and clones to:

  • Accelerate breeding programs
  • Optimize seed orchard design
  • Improve cost-efficiency in plantation establishment

Background & Rationale

  • Aquilaria malaccensis is dioecious: individuals are either male or female.
  • Flowering (which reveals sex) only occurs 3–5 years after planting, causing delays in breeding and seed production planning.
  • Early identification of sex allows:
    • Selection of desired ratios for seed orchards
    • Better allocation of resources and land
    • Avoidance of maintaining non-seed-producing (male) trees in propagation programs
  • Molecular markers offer a non-invasive, lab-based method to detect sex within the first year of growth.

Methodology

  1. Sample Collection
    • Collect leaf samples from sex-identified mature trees (flower-confirmed)
    • Minimum of 20 male and 20 female reference trees
  2. DNA Extraction
    • Standard CTAB or commercial DNA extraction kits
  3. Marker Development
    • Use Random Amplified Polymorphic DNA (RAPD)ISSR, or SCAR markers to find sex-specific alleles
    • Validate with PCR-based screening
  4. Field Testing
    • Apply markers to young, unsexed seedlings
    • Compare results with field sexing as trees mature
  5. Protocol Standardization
    • Develop an SOP for mass screening (with field-lab integration)

Expected Outputs

OutputDescription
✅ Validated molecular markersDNA-based primers for male/female identification
✅ Field-applicable protocolLeaf → DNA → PCR → Sex result
✅ Training materialsFor nursery and lab technicians
✅ Baseline sex ratio dataFrom various farm blocks or seed sources

Applications

  • COPI Tissue Culture Program: Ensure known-sex clones or initiate sex-specific organogenesis
  • CAPI Plantations: Strategic planting of female trees for seed orchards
  • Seedling Certification: Tagging male/female seedlings for investors and growers
  • Research & Policy Support: Contribute to national Aquilaria germplasm conservation and selection

Partners & Stakeholders

  • Cavite State University (CvSU)
  • COPI (R&D and lab implementation)
  • AGAP & AGAC (field validation and adoption)
  • DENR–FPRDI or PCAARRD (for research funding support)

Funding & Timeline

  • Estimated Budget: ₱800,000 – ₱1.2M (equipment, reagents, field validation)
  • Duration: 12 months
  • Optional Funding Sources: DOST-PCAARRD, DA-BAR, private investors
