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

NS

• 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.

BS

• 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.

FS

• Foundation seed is progeny of breeder seed.
• It is also produced from foundation seeds.
• The colour tag of foundation seed is white.

CS

• 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

• Cereals
• Gram
• Lentil

Question 07: What are some examples of epigeal germination?

Answer: Examples of epigeal germination are as follows

• Mustard
• Sunflower
• Castor
• Onion

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

Seed science

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.
