Emasculation is related to
(a) Pure line
(b) Mass selection
(c) Clonal selection
(d) Hybridisation

Options

A. Pure line
B. Mass selection
C. Clonal selection
D. Hybridisation

Answer

**Step-by-Step Solution:**

1. **Understanding Emasculation**: Emasculation is the process of removing the anthers from a flower. This is done to prevent self-fertilization and to control the fertilization process.

2. **Context of Emasculation**: This process is typically performed on bisexual flowers, which contain both male (stamens) and female (pistils) reproductive structures. By removing the anthers, the flower can no longer produce its own pollen.

3. **Purpose of Emasculation**: The primary purpose of emasculation is to facilitate hybridization. By removing the anthers, the plant can be cross-pollinated with pollen from a different, desired parent plant. This is crucial in breeding programs aimed at developing superior varieties.

4. **Analyzing the Options**:
- (a) **Pure line**: This refers to a breeding line that is genetically uniform for specific traits and does not involve hybridization, so emasculation is not relevant here.
- (b) **Mass selection**: This is a method of selecting individuals based on their phenotypic traits, not directly related to emasculation.
- (c) **Clonal selection**: This involves selecting individuals based on their genetic makeup without the need for emasculation.
- (d) **Hybridization**: This is the correct option as emasculation is directly related to the process of hybridization, allowing for controlled cross-pollination.

5. **Conclusion**: Based on the analysis, the correct answer is (d) Hybridization.
