Which method of plant breeding resulted in the production of hessian fly resistant wheat variety ?

Options

A. intrageneric hybridization
B. back cross
C. bulk mehtod
D. intraspecific hybridization

Answer

**Step-by-Step Solution:**

1. **Understanding the Problem**: The question asks for the method of plant breeding that led to the development of a wheat variety resistant to the hessian fly, a significant pest affecting wheat crops.

2. **Identifying the Pest**: The hessian fly is known to damage wheat crops, leading to decreased yields. Therefore, creating a resistant variety is essential for improving wheat production.

3. **Exploring Plant Breeding Methods**: There are various methods of plant breeding, including hybridization. Hybridization can be categorized into simple hybridization, distant hybridization, and intragenic hybridization.

4. **Defining Intragenic Hybridization**: Intragenic hybridization refers to the crossing of individuals from the same genus but different species. This method aims to combine desirable traits, such as pest resistance, from one species into another.

5. **Conclusion**: The method of plant breeding that resulted in the production of hessian fly resistant wheat variety is **intragenic hybridization**. This method is effective in producing resistant varieties by utilizing genetic material from closely related species.
