- Breeder seed (BS); Foundation Seed (FS); and Certified Seed
Production of Certified Seed
- Foundation seed should be planted to produce certified seed
- Distance Isolation 3 m
- Rogueing should be done properly
- Harvest should be done when seed is mature. Some indication
of seed maturity are inner side of the pod turned to dark, and
the Pod texture can be seen clearly
- Field inspection is conducted by seed officer before planting,
vegetative, generative, and close to harvest
Seed Cleaning, drying and storage is done in seed
warehouse
- Clean the pod from soil
- Dry properly (mc < 10%)
Seed Testing
- Moisture content, physical purity, and germination rate is
determined by seed analyst in Seed laboratory.
- Laboratory standard of FS and Certified seed can be seen
in Table 1.
