Question: In the bulk method of plant breeding, how are the bulk populations handled?
Options:
Space-planted
Densely planted
Planted at commercial rates
Also grown in off-season nurseries
✅Explanation:• The bulk method is a plant breeding technique that involves growing and harvesting large populations of plants in bulk. The key feature of this method is that the seeds from each generation are mixed together and planted at normal commercial planting rates. This allows for natural selection to occur within the population, promoting the survival and reproduction of plants with desirable traits.
📌 Other options Explanation:• (A) Space-planting involves planting individual plants at a wider spacing than normal to allow for more individual growth and development.• (B) Dense planting involves planting individual plants closer together than normal to increase competition for resources. This can be used in the bulk method to select for plants that are better able to compete under stressful conditions.• (D) Growing plants in off-season nurseries is not a necessary part of the bulk method. However, it can be used to accelerate the breeding process by allowing for additional generations to be grown in a shorter period of time.
