Question

Arrange the correct sequence of the following classes of seed for a five generation model of vegetable seed production: A. Foundation Seed (Stage-II), B. Breeder Seed, C. Foundation Seed (Stage-I), D. Certified Seed (Stage-II), E. Certified Seed (Stage-I).

• A. B, C, A, E, D
• B. A, B, C, D, E
• C. B, A, C, D, E
• D. C, D, A, B, E

Hint:

Five generation seed production sequence is Breeder Seed \(\rightarrow\) Foundation Seed Stage-I \(\rightarrow\) Foundation Seed Stage-II \(\rightarrow\) Certified Seed Stage-I \(\rightarrow\) Certified Seed Stage-II.

Answer 1

The Correct Option is A

Concept:
Seed production follows a fixed generation sequence to maintain genetic purity and seed quality.

Step 1: Start with breeder seed.
Breeder seed is produced under the direct supervision of the breeder and is the source seed for further multiplication. \[ \text{First step}=B \]

Step 2: Foundation Seed Stage-I.
Foundation seed stage-I is produced from breeder seed. \[ \text{Second step}=C \]

Step 3: Foundation Seed Stage-II.
Foundation seed stage-II is produced from foundation seed stage-I. \[ \text{Third step}=A \]

Step 4: Certified Seed Stage-I.
Certified seed stage-I is produced from foundation seed. \[ \text{Fourth step}=E \]

Step 5: Certified Seed Stage-II.
Certified seed stage-II is the next multiplication stage. \[ \text{Fifth step}=D \] Thus, the correct sequence is: \[ B,C,A,E,D \] \[ \therefore \text{Correct Answer is (A)} \]
