Which of the following is an example of intergeneric hybridization ?

Options

A. Triticale
B. Raphanobrassica
C. ADT-37
D. More than one option is correct

Answer

To solve the question "Which of the following is an example of intergeneric hybridization?", we can follow these steps:

### Step-by-Step Solution:

1. **Understand Intergeneric Hybridization**:
- Intergeneric hybridization refers to the crossing of plants from different genera within the same family. This means that while the plants belong to the same family, they must be from different genera.

2. **Identify the Examples Given**:
- The question provides several examples that we need to analyze to determine if they fit the criteria of intergeneric hybridization.

3. **Analyze Each Example**:
- **Triticale**: This is a hybrid between wheat (Triticum) and rye (Secale). Since wheat and rye belong to different genera but the same family (Poaceae), this is an example of intergeneric hybridization.
- **Raffano Brassica**: This hybrid is between Brassica (which includes cabbage and mustard) and Raphanus (radish). Again, these belong to different genera within the same family (Brassicaceae), making this another example of intergeneric hybridization.
- **ADT 37**: This is a hybrid between two varieties of rice, specifically Oryza japonica and Oryza indica. Since both belong to the same genus (Oryza), this does not qualify as intergeneric hybridization.

4. **Conclusion**:
- Based on the analysis, both Triticale and Raffano Brassica are examples of intergeneric hybridization, while ADT 37 is not. Therefore, the correct answer includes Triticale and Raffano Brassica.

### Final Answer:
The examples of intergeneric hybridization are Triticale and Raffano Brassica.
