Biofortification: Key Aspects and Examples for Class 12th

Golden Rice: This is one of the most well-known examples of biofortification. Golden Rice is genetically modified to produce beta-carotene, a precursor to vitamin A. It helps combat vitamin A deficiency, a major health issue in many developing countries.
Iron-Biofortified Beans: Iron deficiency anaemia is a widespread health problem, especially among women and children. Iron-biofortified beans are bred to have higher levels of iron, making them a more nutritious food source.
Zinc-Biofortified Wheat: Wheat is a staple crop for many people, but it often lacks essential nutrients like zinc. Zinc-biofortified wheat varieties are developed to provide higher levels of zinc, addressing zinc deficiency.

Plant Breeding: Definition, Experiments, Aims, varieties and steps in Plant breeding

Plant breeding is the practice of modifying a plant’s genetic composition to achieve desired traits. Genetic engineering, cross-breeding, and selective breeding are used to accomplish this. Plant breeders work to create plants with desirable characteristics, such as increased nutritional value, disease resistance, drought tolerance, or higher production.
