Question

Which one of the following factors influences the determination of isolation distance requirements in cross-pollinated crops?

• A. Plant height
• B. Germination rate
• C. Soil fertility
• D. Type of pollinating agent

Hint:

To remember:
- Self-pollinated crops (e.g., Wheat, Rice) require very small isolation distances (typically only 3 meters) to prevent mechanical mixing during harvest.
- Cross-pollinated crops (e.g., Maize) require large isolation distances (up to 400--1,000 meters) to prevent pollen contamination.

Answer 1

The Correct Option is D
