उत्तर १
Biofortification is the method of breeding crops to produce varieties which have increased nutritional value.
उत्तर २
Biofortification is a process of breeding crops with higher levels of vitamins, minerals, proteins, and fat content. This method is employed to improve public health. Breeding of crops with improved nutritional quality is undertaken to improve the content of proteins, oil, vitamins, minerals, and micronutrients in crops. It is also undertaken to upgrade the quality of oil and proteins. An example of this is a wheat variety known as Atlas 66, which has high protein content in comparison to the existing wheat. In addition, there are several other improved varieties of crop plants, such as rice, carrots, spinach, etc., which have more nutritious value and more nutrients than the existing varieties.
