Practicing Success
Which of the following vegetables has been enriched with vitamin A? |
Carrots, spinach, and pumpkin Bitter gourd and mustard Bathua and tomatoes Broad beans and French beans |
Carrots, spinach, and pumpkin |
The correct answer is Option (1) -Carrots, spinach, and pumpkin Biofortification – breeding crops with higher levels of vitamins and minerals, or higher protein and healthier fats – is the most practical means to improve public health. Breeding for improved nutritional quality is undertaken with the objectives of improving – (i) Protein content and quality; (ii) Oil content and quality; (iii) Vitamin content; and (iv) Micronutrient and mineral content. In 2000, maize hybrids that had twice the amount of the amino acids, lysine and tryptophan, compared to existing maize hybrids were developed. Wheat variety, Atlas 66, having a high protein content, has been used as a donor for improving cultivated wheat. It has been possible to develop an iron-fortified rice variety containing over five times as much iron as in commonly consumed varieties. The Indian Agricultural Research Institute, New Delhi has also released several vegetable crops that are rich in vitamins and minerals, e.g., vitamin A enriched carrots, spinach, pumpkin; vitamin C enriched bitter gourd, bathua, mustard, tomato; iron and calcium enriched spinach and bathua; and protein enriched beans – broad, lablab, French and garden peas. |
