Which of the following is not an objective of Biofortification in crops?

The correct answer is Improve resistance to diseases.

Explanation:

Biofortification is the process of breeding crops with higher levels of vitamins, minerals, proteins, and healthier fats to improve public health. Its primary goal is to address nutritional deficiencies (hidden hunger) in human populations.

The main objectives of biofortification include:

1. Improving protein content and quality.

2. Improving oil content and quality.

3. Improving vitamin content (e.g., Vitamin A enriched rice/Golden Rice).

4. Improving micronutrient and mineral content (e.g., Iron and Zinc enriched wheat or rice).

On the other hand, breeding for resistance to diseases, pests, or environmental stress (like drought or salinity) falls under conventional crop protection and stress resistance breeding, not biofortification, as it focuses on crop yield and survival rather than enhancing the nutritional profile of the edible parts.

Therefore, Improve resistance to diseases is not an objective of biofortification.
