C. Germination test
D. Freedom from weeds and diseases
Choose the correct answer from the options given below:
A. Genetic purity
B. Physical purity
C. Germination test
D. Freedom from weeds and diseases
Choose the correct answer from the options given below:
Show Hint
1. Genetic Purity (True-to-type)
2. Physical Purity (Cleanliness)
3. Physiological Quality (Germination & Vigor)
- A, B, and D only
- A, B, and C only
- A, C, and, D only
- B, C, and D only
The Correct Option is B
Solution and Explanation
Seed quality is determined by multiple physical, physiological, and genetic parameters.
For any seed lot to be certified, it must meet the minimum seed standards specified under seed certification rules.
Step 2: Detailed Explanation:
The three core pillars of seed quality evaluated for official certification are:
A. Genetic purity: Ensures that the seeds are true-to-type and belong specifically to the declared variety, preserving yield potential and agronomic traits.
B. Physical purity: Measures the percentage of pure seed in the lot, ensuring it is free from inert matter (dirt, stones, chaff), other crop seeds, and weed seeds.
C. Germination capacity: Measures the percentage of seeds capable of producing normal seedlings under favorable conditions, ensuring proper plant stand establishment in the field.
These three parameters are quantitatively tested and printed on the official certification tag.
While freedom from designated weeds and seed-borne diseases (D) is highly important during field inspections and represents a component of field standards, the primary laboratory standards that must be met to avoid a lot being classified as "substandard" are physical purity, germination, and genetic purity.
Therefore, A, B, and C are the primary requirements.
Step 3: Final Answer:
The core requirements for seed certification are genetic purity, physical purity, and germination.
Therefore, the correct option is (B).
