Rate of success in artificial hybridization is

Options

A. only one in few hundred to a thousand crosses
B. only hundred in few hundred to a thousand crosses
C. only thousand in few thousands to a million crosses
D. none

Answer

### Step-by-Step Solution:

1. **Understanding Artificial Hybridization**:
- Artificial hybridization is a technique in plant breeding where two different plants are crossed to produce a hybrid. The goal is to combine desirable traits from both parent plants into the offspring.

2. **Process of Artificial Hybridization**:
- The process begins with the selection of parent plants. These plants are evaluated based on their traits and characteristics.
- Once suitable parents are chosen, cross hybridization is performed. This involves transferring pollen from one plant to the stigma of another to facilitate fertilization.

3. **Challenges in Hybridization**:
- The hybridization process is time-consuming and labor-intensive.
- There is no guarantee that the resulting hybrids will exhibit the desired traits.

4. **Statistical Success Rate**:
- According to statistics, the success rate of obtaining a hybrid with the desired traits is low. Specifically, it is noted that in every 100 to 1000 crosses, only one hybrid is likely to possess the desired characteristics.

5. **Evaluating the Options**:
- Given the options:
- Option 1: Only 1 in few hundred to thousand crosses (this matches the statistical success rate mentioned).
- Option 2: Only 100 in few hundred to thousand crosses (incorrect).
- Option 3: Only 1000 in few thousand to million crosses (incorrect).
- Option 4: None (incorrect).
- The correct answer is Option 1.

6. **Conclusion**:
- The rate of success in artificial hybridization is best represented by Option 1: only 1 in few hundred to thousand crosses.
