In an artificial hybridization program with dioecious plants:
- Bagging of the female flower: Relevant to prevent unwanted pollen contamination.
- Dusting of pollen on the stigma: Essential for pollination to occur.
- Emasculation: Not relevant because dioecious plants have separate sexes; emasculation is for monoecious plants.
- Collection of pollen: Necessary for controlled pollination process.
Therefore, in this context, the step that would not be relevant is C: Emasculation.
Topic in NCERT: Artificial Hybridization Techniques
Line in NCERT: "Emasculated flowers have to be covered with a bag of suitable size, generally made up of butter paper, to prevent contamination of its stigma with unwanted pollen."
- Bagging of the female flower: Relevant to prevent unwanted pollen contamination.
- Dusting of pollen on the stigma: Essential for pollination to occur.
- Emasculation: Not relevant because dioecious plants have separate sexes; emasculation is for monoecious plants.
- Collection of pollen: Necessary for controlled pollination process.
Therefore, in this context, the step that would not be relevant is C: Emasculation.

Understanding Dioecious Plants
Dioecious plants have distinct male and female individuals, meaning that for hybridization, both types are necessary. In the context of artificial hybridization in these plants, certain steps are crucial while others may not be relevant.
Steps in Artificial Hybridization
- Bagging of the Female Flower:
This step is essential to prevent unwanted pollination from external pollen. It ensures that only the desired pollen is used for fertilization.
- Dusting of Pollen on the Stigma:
This step is critical as it involves transferring pollen from the male flower to the stigma of the female flower, facilitating fertilization.
- Collection of Pollen:
This step is relevant in preparation for hybridization as it involves gathering pollen from male plants for later use.
Why Emasculation is Not Relevant
- Emasculation:
This process refers to the removal of male reproductive organs (anthers) from flowers. In dioecious plants, this step is not applicable because male and female flowers exist on separate plants. Therefore, there are no male organs to remove from the female flower, making emasculation irrelevant in this context.
Conclusion
In summary, while bagging, dusting of pollen, and collecting pollen are essential steps in the hybridization of dioecious plants, emasculation does not apply due to the nature of their reproductive structure. Understanding these processes is crucial for successful hybridization programs.
