In wheat, production of certified seed needs an isolation distance of____________________?
Correct answer: C. 3 Meters
- A. 5 Meters
- B. 4 Meters
- C. 3 Meters
- D. 2 Meters
Explanation
Wheat is largely self-pollinated, so only a small isolation distance is needed to prevent mechanical mixing or occasional outcrossing; the certified-seed standard is 3 metres. Larger distances are generally associated with less self-pollinated crops or higher seed classes.
