Which one is the problems of hybrid seeds?

Options

A. Progeny segregate and do not maintain hybrid characters.
B. Production of hybrid seeds is costly
C. Hybrid seeds have to be produced every year
D. all of these

Answer

### Step-by-Step Solution:

1. **Understanding Hybrid Seeds**: Hybrid seeds are produced through the process of hybridization, where two different parent plants with desirable traits are crossed to create a new plant variety that ideally possesses the best traits of both parents.

2. **Problem of Segregation**: One major problem with hybrid seeds is that when they are planted, the seeds produced in the next generation (after sexual reproduction) may not retain the desirable traits of the hybrid parent plants. This is due to the genetic segregation that occurs during reproduction, leading to variations in the offspring.

3. **Cost of Production**: The production of hybrid seeds is often costly. The process of hybridization involves selecting parent plants with desirable traits, crossing them, and then selecting the best progeny. This process can be time-consuming and expensive.

4. **Need for Annual Production**: Since hybrid seeds do not produce offspring that maintain the same desirable traits, farmers must produce new hybrid seeds every year. This means that farmers cannot save seeds from their harvest for the next planting season, which adds to the cost and effort involved in farming.

5. **Conclusion**: All of the above-mentioned points highlight the problems associated with hybrid seeds: the issue of trait segregation, high production costs, and the necessity to produce new seeds each year. Therefore, the correct answer to the question is that all these points represent problems of hybrid seeds.
