Answer

To arrange the events observed in an artificial hybridization program in the correct sequential order, we can follow these steps:

1. **Selection of Parents (Step 2)**: The first step in artificial hybridization is to select the parent plants that possess desirable traits. This selection is crucial as it determines the potential success of the hybrid.

2. **Emasculation (Step 5)**: After selecting the parents, the next step is emasculation. This involves the removal of the anthers from the female parent flower to prevent self-pollination.

3. **Bagging (Step 3)**: Once emasculation is done, the flower is bagged to protect it from unwanted pollen and to ensure that only the desired pollen is used for fertilization.

4. **Collection of Pollen from Male Parent (Step 6)**: After bagging, pollen is collected from the male parent flower. This pollen will be used to fertilize the female parent.

5. **Dusting the Pollen on Stigma (Step 4)**: The collected pollen is then dusted onto the stigma of the emasculated flower of the female parent, facilitating fertilization.

6. **Re-bagging (Step 1)**: Finally, after pollination, the flower is re-bagged to protect the developing seeds from external factors.

Thus, the correct sequential order of the events is:
2. Selection of parents
5. Emasculation
3. Bagging
6. Collection of pollen from male parent
4. Dusting the pollen on stigma
1. Re-bagging

The final sequence is: **2, 5, 3, 6, 4, 1**.
