SEED CERTIFICATION STANDARDS

SEED CERTIFICATION STANDARDS
Field Inspection
a. Mother bulb production stage: A minimum of two inspections should be done as follows:

• The first inspection should be done after transplanting of seedlings in order to determine isolation, volunteer plants, off-types including bolters and other relevant factors
• The second inspection should be done after the bulbs have been lifted to verify the true characteristics of bulb.

b. Seed production stage: A minimum of four inspections shall be made as follows

• The first inspection should be done before flowering in order to determine isolation, volunteer plants, off- types including bolters and other relevant factors
• The second and third inspection should be during flowering to check isolation, off types and other relevant factors.
• The fourth inspection should be at maturity to verify the true nature of the plant and other relevant factors.
