Discribe five parameters in seed quality control conducted by seed control certification institute? ?

1. Germination rate: This parameter measures the percentage of seeds that successfully germinate under controlled conditions. A high germination rate indicates good seed quality.

2. Purity: Purity refers to the percentage of seeds in a sample that belong to the desired species. Contaminants such as weed seeds, other crop seeds, or inert matter can reduce the quality of the seed lot.

3. Moisture content: The moisture content of seeds is an important factor in determining their viability and storability. Seeds with high moisture content are more prone to fungal growth and deterioration.

4. Seed health: Seed health testing involves checking for the presence of pathogens such as fungi, bacteria, and viruses that can affect seed quality and crop performance.

5. Genetic purity: Genetic purity testing ensures that the seeds in a lot are true to type and free from genetic impurities or cross-contamination. This is particularly important for maintaining the integrity of hybrid varieties.

1. Physical Purity: Assesses the percentage of pure seed, free from other crop seeds, weed seeds, and inert matter.
2. Varietal Purity: Determines the percentage of crop seeds belonging to the desired variety, as specified in the certification standards.
3. Germination: Measures the percentage of seeds that produce normal seedlings under controlled conditions, indicating seed viability.
4. Moisture Content: Ensures that seeds have an appropriate moisture level for storage and planting, preventing deterioration and maintaining seed quality.
5. Seed Health: Detects the presence of disease-causing pathogens or insects that may affect seed performance or plant health during cultivation.
