Regarding the pros and cons of hybrid rice:

Advantages:
1. High yield: This is the greatest value of hybrid rice, typically increasing production by 10%–30% compared to conventional varieties.
2. Stronger stress resistance: Some hybrid combinations show better adaptability to pests, diseases, lodging, and environmental changes.
3. Improves food security: Especially during periods of rapid population growth, it has significantly enhanced food supply capacity.
4. Promotes the development of modern breeding: It has driven progress in the entire agricultural breeding system.

Disadvantages:
1. Farmers cannot save seeds; they typically need to purchase seeds each year.
2. Reduces agricultural genetic diversity, increasing the risk of vulnerability to new pests and diseases, and potentially weakening ecosystem resilience.
3. More dependent on modern agricultural systems, so it is not the optimal solution for all regions.

Unconfirmed:
Causes infertility, alters human genes, affects offspring fertility, and is less safe than ordinary rice.
