Hint:

To remember sample sizes for the Grow-Out Test (GOT):
Large/heavy seeds (Groundnut) = \( 1000\text{ g} \).
Medium seeds (Paddy, Wheat) = \( 500\text{ g} \).
Small seeds (Jute, Brassica) = \( 100\text{ g} \).
Vegetative propagation (Sweet potato) = 250 tubers.

Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
The Grow-Out Test (GOT) is the definitive method used to determine the genetic purity of a seed lot.
It involves growing plants from a representative seed sample to maturity under controlled field conditions and comparing their morphological characteristics against standard varietal descriptors.
The sample size submitted for a GOT depends on the seed size, sowing rate, and planting material of the crop.

Step 2: Detailed Explanation:
Let us correlate each crop with its standard sample size required for conducting a Grow-Out Test under official seed certification rules:
1. Groundnut (A):
Groundnut (Arachis hypogaea) produces large, heavy seeds (pods/kernels).
Because of their size and weight, a larger sample mass is required to provide a representative number of plants for the test.
The standard sample size is \( 1000\text{ g} \) (1.0 kg).
Thus, (A) matches with (II).
2. Paddy (B):
Paddy (Oryza sativa) has medium-sized seeds.
A sample of \( 500\text{ g} \) provides a sufficient number of seeds (approximately 15,000 to 20,000 seeds) to raise a representative plot for genetic purity evaluation.
Thus, (B) matches with (III).
3. Jute (C):
Jute (Corchorus spp.) has very small, lightweight seeds.
A small sample size of \( 100\text{ g} \) provides more than enough seeds to establish the required plant population for DUS/GOT evaluations.
Thus, (C) matches with (IV).
4. Sweet potato (D):
Sweet potato (Ipomoea batatas) is vegetatively propagated using tubers or vine cuttings rather than true seeds.
Therefore, the test sample is submitted as vegetative planting material. The standard sample size is 250 tubers.
Thus, (D) matches with (I).

Step 3: Final Answer:
The correct matching sequence is (A)-(II), (B)-(III), (C)-(IV), and (D)-(I). This corresponds to option (D).
