Hybrid breeding have led to the development of several high yielding varieties that are

Options

A. resistant to drought stress
B. resistant to water stress
C. resistant to chemical stress
D. both (a) and (b)

Answer

To solve the question regarding hybrid breeding and the development of high-yielding varieties, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Hybrid Breeding**: Hybrid breeding involves crossing different varieties of plants to produce offspring that exhibit desirable traits, such as higher yields or resistance to environmental stresses.

2. **Identifying the Plant**: The question specifically asks about the plant in which hybrid breeding has led to the development of high-yielding varieties. In this case, the millet plant is identified as the focus of hybrid breeding efforts.

3. **Assessing the Conditions**: The hybrid varieties developed through this breeding process are designed to withstand challenging environmental conditions. The key conditions mentioned are drought resistance and water stress resistance.

4. **Conclusion**: Based on the information provided, the high-yielding varieties developed through hybrid breeding in millet are characterized by their resistance to both drought and water stress. Therefore, both conditions are correct.

5. **Selecting the Correct Answer**: Since both conditions (A: resistance to drought and B: resistance to water stress) are applicable, the correct answer would be the option that includes both A and B.

### Final Answer:
The correct answer is that hybrid breeding has led to the development of several high-yielding varieties that are resistant to drought and water stress.
