Tomatoes are globally popular but highly seasonal. Rainy seasons bring flooding risks and disease proliferation (blossom end rot, fruit rot, early blight). Researchers at the Philippines' Bureau of Plant Industry developed grafting technology for off-season production—now commercially available.
Grafting tomatoes onto eggplant rootstock (EG-203 variety) eliminates bacterial wilt, a devastating tomato disease. Research shows 21% higher yields versus conventional seedlings.
Method: Sow eggplant seeds 5-7 days before tomatoes. Graft at 3-4 weeks. Cut stock and scion at matching 70-80° angles above cotyledons with sterilized blade. Join with 10mm rubber tubing (1-1.5cm diameter). Place in humidity chamber, then 4-7 days in cool, dark, net-covered area before transplanting.
Rootstock: EG-203 eggplant—highly resistant to bacterial wilt and soil-borne diseases.
Scion: Indeterminate tomato varieties requiring trellising for optimal development.
This technology enables continuous fresh tomato harvests during rainy seasons—valuable for commercial growers and hobbyists alike.
