Seed science questions: 01-05
Question 01: What is seed?
Answer: Seed is a fertilized ovule consisting of intact embryo, food, and seadcoat. It is viable and has capacity to germinate in a favourable conditions.
Question 02: What are the different types of seed?
Answer: The different types of seeds are as follows
- Nucleus seed
- Breeder seed
- Foundation seed
- Certified seed
- Nucleus seed is pure seed.
- Genetically, it is 100 percent pure
- It does not contain other physical impurities.
- Tag colour of nucleus seed is golden yellow.
- Breeder seed is produced by the plant breeders. It is the progeny of nucleus seed. It does not have 100 percent genetic purity. If used in a seed production programme, subsequent generation shall confirm to the prescribed standards of genetic purity. It is 99.9-100% pure.
- The colour tag of breed seed is yellow.
- Foundation seed is progeny of breeder seed.
- It is also produced from foundation seeds.
- The colour tag of foundation seed is white.
- Certified seed is progeny of foundation seed.
- Specific genetic identity and purity is maintained.
- Certified seed may be the progeny of certified seed, but reproduction should not exceed three generations.
Question 03: What are the tag colours of different seeds?
Answer: The tag colours of different seeds are as follows
- Nucleus seed: Golden yellow
- Breeder seed: Yellow
- Foundation seed: White
- Certified seed: Blue
Question 04: Who produces foundation seed?
Answer: Foundation seeds are produced by the National Seed Corporation.
Question 05: Who produces certified seed?
Answer: Certified seeds are produced by the State Seed Corporation.
Seed technology questions: 06-10
Question 06: What are some examples of hypogeal germination?
Answer: Examples of hypogeal germination are as follows
Question 07: What are some examples of epigeal germination?
Answer: Examples of epigeal germination are as follows
Question 08: How is varietal purity checked?
Answer: Varietal purity is checked by Grow Out Test.
Question 09: What is dockage?
Answer: It is the impurity percentage of seed.
Question 10: What is the formulae of real value of seed?
Answer: The formulae of real value of seed is
(Purity % × Germination %) / 100
Question 11: What is seed viability?
Answer: It is the capacity of the seed to germinate.
Question 12: Which chemical is used for seed viability test?
Answer: 2, 3, 5-triphenyl tetrazolium chloride is used for seed viability test.
Question 13: When was National Seed Project started?
Answer: National Seed Project was started in 1988.
Question 14: How would you break the seed dormancy of potato tubers?
Answer: By using 1% of thiourea.
Question 15: Which is the most common plant growth regulator to initiate seed germination?
Answer: Gibberellic acid is the most common plant growth regulator to initiate seed germination.
Question 16: What is stratification?
Answer: It is the pre-treatment of seeds to break dormancy which is due to low temperature and moisture conditions.
Question 17: What is scarification?
Answer: It is the pre-treatment of seeds to break dormancy which is due to hard or impermeable seed coat.
Question 18: What is the formulae of pure live seed?
Answer: The formulae of pure live seed is
(Purity % × Viability %) / 100
Question 19: What is the main aim of maintaining isolation distance?
Answer: The main aim of maintaining isolation distance is to avoid contamination or cross pollination.
Question 20: What is the isolation distance for self pollinated crops?
Answer: The isolation distance for self pollinated crop is 3 m.

Question 21: What is the isolation distance for certified maize?
Answer: The isolation distance for certified maize is 200 m.
Question 22: What is test weight?
Answer: It is the weight of 1000 seeds
Question 23: What is seed index?
Answer: It is the weight of 100 seeds.
Question 24: When was seed act passed?
Answer: Seed act was passed in 1966.
Question 25: What is grading?
Answer: The processing of seed is known as grading.
