Question

Arrange various types of seeds in order of genetic purity and production.
A. Breeders seed
B. T L seeds
C. Nucleus seeds
D. Certified seeds
E. Foundation seeds
Choose the correct answer from the options given below:

• A. C-A-E-D-B
• B. C-A-E-B-D
• C. A-C-D-E-B
• D. A-C-E-B-D

Hint:

Seed generation chain: Nucleus ($100\%$) $\to$ Breeder ($100\%$, Golden Yellow) $\to$ Foundation ($99.5\%$, White) $\to$ Certified ($99\%$, Blue) $\to$ TL Seed (Green).

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
The recognized seed multiplication generation system in India follows a hierarchical order to preserve varietal genetic purity.

Step 2: Detailed Explanation:
The generation system from highest genetic purity and initial production to downstream commercial seed classes is:
1. Nucleus Seed (C): $100\%$ genetic purity, produced directly by the originating plant breeder.
2. Breeder Seed (A): $100\%$ genetic purity, progeny of nucleus seed, tagged with Golden Yellow tag.
3. Foundation Seed (E): $\ge 99.5\%$ genetic purity, progeny of breeder seed, certified by SSCA with White tag.
4. Certified Seed (D): $\ge 99.0\%$ genetic purity, progeny of foundation seed sold to commercial farmers, Azure Blue tag.
5. Truthfully Labelled (TL) Seed (B): Tested and labelled by producer without formal statutory certification, Opal Green tag.

Step 3: Final Answer:
Thus, the correct sequence is C-A-E-D-B.
