Final answer:
The most efficient way to generate more plants with a desirable flower trait is cloning the plant.
Step-by-step explanation:
The most efficient way to generate more plants with a desirable flower trait would be to clone the plant. Cloning involves taking a cutting from the original plant and growing it into a new plant with the exact same genetic characteristics. This ensures that all the new plants will have the desired flower trait.
Self-pollination would not guarantee the same trait in the offspring as it depends on the genetic variation within the plant.
Backtracking through previous experiments and crossing two plants would introduce more genetic variation and may not result in all the offspring having the desirable trait.
Breeding this plant with another plant that does not flower would not guarantee the same trait in the offspring unless the non-flowering plant has the specific genetic makeup required for the desirable trait.
