In case of millets, hybrid breeding have led to the development of several high yielding varietes specifically resistant to:

Options

A. Insects
B. Drought
C. Pests
D. Nematodes

Answer

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks about the specific resistances developed in high yielding varieties of millets through hybrid breeding.

2. **Identifying Hybrid Breeding**: Hybrid breeding involves crossing different varieties to produce offspring that exhibit desirable traits, such as higher yield and resistance to various environmental factors.

3. **Recognizing the Conditions for Millet Growth**: Millets are typically grown in warm environments and are often cultivated in soils that are poor in nutrients. This is important as it sets the context for the challenges faced by millet crops.

4. **Challenges Faced by Millets**: In poor soil conditions, millets are susceptible to various stresses, including drought. Drought is a significant challenge that can severely impact the yield of millets.

5. **Benefits of Hybrid Breeding**: Through hybrid breeding, scientists have developed high yielding varieties of millets that are specifically bred to withstand adverse conditions, particularly drought. This means that these varieties can survive and produce better yields even when water is scarce.

6. **Conclusion**: Based on the understanding of hybrid breeding and the environmental conditions affecting millets, the high yielding varieties developed are specifically resistant to drought.

### Final Answer:
In case of millets, hybrid breeding has led to the development of several high yielding varieties specifically resistant to **drought**.
