Summary
ICAR-Central Potato Research Institute has developed Kufri Jamunia (MSP/16-307), a purple-fleshed potato with more vitamin C, anthocyanins, zinc and iron than regular potatoes. The Union government has promoted it as a tool against hidden hunger, where diets supply enough calories but too few micronutrients.
CPRI's trial data, however, show its marketable yield trailing Kufri Neelkanth. It is susceptible to late blight in the field and farmers would need about a 15 per cent price premium to earn the same gross revenue. With seed already 40-50 per cent of production costs and consumer acceptance of a purple potato untested at scale, the variety's nutrition depends on economics as much as on breeding.
WHY IT MATTERS FOR UPSC & STATE PCS
The Hindu analysed the Kufri Jamunia potato, which the Centre has promoted against hidden hunger. Its analysis set the variety's nutrient gains against CPRI's yield, disease and consumer-test data.

A Nutrient in a Seed Must Pass Three Filters Before It Reaches a Body
Here's what is actually happening with any biofortified crop. Scientists breed extra nutrients into a plant, but that nutrient only fights hidden hunger if it passes three filters. First, a farmer has to choose to grow it.
Second, a household has to buy it, cook it and eat it regularly. Third, the body has to absorb the nutrient that survives cooking. Kufri Jamunia clears the laboratory with ease. The real question is the three filters.
What the Breeding Achieved ICAR-Central Potato Research
Institute created Kufri Jamunia by crossing a line high in vitamin C with a purple-fleshed line. According to PIB, 100 g of its flesh contains about 42.75 mg of vitamin C against 23.15 mg in regular potatoes, 2.28 mg of zinc against 0.28 mg and 3.22 mg of iron against 0.57 mg.
It also contains anthocyanins, the pigments that give jamun and blueberries their colour. In a country where NFHS-5 found 57 per cent of women and 67.1 per cent of young children anaemic, those numbers matter.
Filter One: The Field
The first filter is where Kufri Jamunia struggles. CPRI's multi-location trial data put its marketable yield at 29.19 tonnes per hectare, against 33.48 for Kufri Neelkanth, an existing CPRI variety. Its overall mean yield of 31.96 t/ha hides a wide spread: 36.77 in north India but only 25.91 in the east.
It resisted late blight moderately in the laboratory but proved susceptible in the field and CPRI recommends fungicide. The arithmetic for a farmer is simple. With equal costs, Kufri Jamunia would need about a 15 per cent price premium to match Neelkanth's gross revenue.
Seed is already 40-50 per cent of potato production costs or roughly ₹60,000-75,000 per hectare by CPRI's 2020 estimate. A farmer will not pay more to risk earning less.
Filters Two and Three: The Plate and the Body
The second filter is consumer acceptance. In a CPRI test with 64 people, 95 per cent rated its overall acceptability good to excellent. But 64 people is too small a sample to predict how buyers in a mandi will respond to a purple potato, when ordinary potatoes sell for about ₹17 per kg wholesale.
The third filter is the body. Cooking matters: a 2016 study on purple-fleshed potatoes found steaming and microwaving preserved more nutrients than stir-frying, but no such study exists for this variety. In principle, vitamin C helps the body absorb iron from plants and Kufri Jamunia contains both.
Whether that actually improves iron status in people who eat it has not been studied.
The Lesson From Africa
The orange-fleshed sweet potato, promoted by HarvestPlus in Sub-Saharan Africa, offers a model. It faced resistance at first because of its unfamiliar colour and it succeeded only once seed economics worked for farmers and public campaigns linked its colour to children's health. The lesson is that biofortification works when a nutrient travels inside a crop that farmers already find profitable.
Why This Matters for the Exam
India has released about 130 biofortified varieties. For GS3, the useful insight is that a crop's nutrient profile is only the starting point. Hidden hunger is solved in the field, the market and the kitchen, not in the laboratory alone.
Quick Facts
Key numbers & takeaways — revise these first
-
Kufri Jamunia was developed by ICAR-CPRI, has the formal designation MSP/16-307 and was notified in November 2024.
-
Per PIB, 100 g of its flesh contains about 42.75 mg vitamin C, 42.05 mg anthocyanins, 2.28 mg zinc, 3.22 mg iron and 161 micrograms of carotenoids.
-
Regular potatoes contain about 23.15 mg vitamin C, 0.28 mg zinc and 0.57 mg iron per 100 g. The crop matures in about 90 days, with 10-12 medium to large tubers per plant.
-
Its purple colour comes from anthocyanins, also found in jamun and blueberries.
-
Hidden hunger means getting enough calories but not enough micronutrients.
-
Biofortification breeds nutrients into crops, whereas fortification adds them during processing.
-
Per NFHS-5, 57 per cent of women aged 15-49 and 67.1 per cent of children aged 6-59 months are anaemic.
-
India is the world's second-largest potato producer after China.
