(In artificial hybridization, the correct answer is B: (b), (c), and (d) only. Here's why:
- (b): Emasculation is crucial to prevent self-pollination and ensure only desired pollen reaches the stigma.
- (c): Bagging emasculated flowers post-cross-pollination shields them from unwanted pollen.
- (d): Bagging after anther removal further secures the controlled pollination process by preventing accidental self-pollination.
These steps collectively ensure successful artificial hybridization by controlling pollination and fertilization processes effectively.B)

Understanding Artificial Hybridization in Plants
Artificial hybridization is a crucial technique used in plant breeding, particularly when dealing with unisexual and bisexual flowers. To ensure successful cross-pollination while preventing unwanted pollen contamination, certain steps must be taken.
Key Steps in Artificial Hybridization
- Female Flower Buds:
- The female flower buds of plants producing unisexual flowers need not be bagged. This is because these buds do not produce pollen, making them less susceptible to contamination.
- Emasculation Process:
- There is a need to emasculate unisexual flowers of the selected female parent. Emasculation involves removing the anthers to prevent self-pollination and ensure that only the desired pollen is used for fertilization.
- Bagging After Cross-Pollination:
- Emasculated flowers must be bagged immediately after cross-pollination. This prevents any foreign pollen from reaching the stigma after the desired pollen has been applied.
- Removal of Anthers:
- Emasculated flowers should be bagged after the removal of anthers to ensure that no self-pollination occurs.
- Protogyny Consideration:
- Bisexual flowers showing protogyny are typically avoided for cross-pollination as they can complicate the process due to their timing in sexual maturity.
Conclusion: Why Option B is Correct
Option B, which includes (b), (c), and (d), correctly outlines the necessary steps for successful artificial hybridization:
- Emasculation is essential to prevent self-pollination.
- Immediate bagging after cross-pollination protects against contamination.
- Proper removal of anthers is crucial for ensuring that only the intended pollen is used.
By following these guidelines, breeders can effectively control the pollination process and achieve desired results in plant hybridization.
