Why in News?
A PIB explainer published on 18 October 2026 highlighted Kufri Jamunia, a nutrient-rich purple potato developed by the ICAR–Central Potato Research Institute (CPRI), Shimla.
Released in 2024, the variety reflects efforts to improve the nutritional quality of commonly consumed crops through biofortification. Other coloured potato varieties developed by the institute include Kufri Neelkanth and Kufri Manik.
What Is Kufri Jamunia?
Kufri Jamunia is a biofortified, purple-fleshed table potato variety. A table variety is primarily intended for cooking and direct consumption.
Its distinctive feature is the presence of purple colour in both the skin and flesh, associated with anthocyanin pigments.
Key Characteristics
| Feature | Description |
|---|---|
| Developing institution | ICAR–Central Potato Research Institute, Shimla |
| Release year | 2024 |
| Maturity | Medium-maturing, approximately 90–100 days |
| Tuber appearance | Dark-purple skin and purple flesh |
| Shape | Oblong, with shallow eyes |
| Reported yield potential | Around 32–35 tonnes per hectare under recommended conditions |
| Storage | Good keeping quality |
| Primary use | Table consumption |
Official variety information recommends it for the Northern, Central and Eastern plains, covering several major potato-growing states. Its cultivation recommendation is therefore broader than the northern plains alone.
The variety has a mealy texture, medium-tall plants and a semi-compact canopy. Its dormancy period is approximately 6–8 weeks, while storage trials indicate low rotting and limited weight loss. Dormancy refers to the period during which harvested tubers do not readily sprout.
Why Is Kufri Jamunia Nutritionally Important?
Official descriptions highlight its vitamin C, anthocyanins and carotenoids, along with enhanced iron and zinc content.
| Component | Significance |
|---|---|
| Ascorbic acid | Another name for vitamin C |
| Anthocyanins | Natural pigments associated with red, blue and purple colours; possess antioxidant properties |
| Carotenoids | Plant pigments; some members of this group serve as vitamin A precursors |
| Iron and zinc | Essential micronutrients required for normal body functions |
Important distinction: Anthocyanins are plant compounds, not vitamins or minerals. Their presence adds nutritional interest, but colour alone does not establish the complete nutritional value of a food.
The contribution of a biofortified crop to human nutrition also depends on the quantity consumed, nutrient retention during cooking and the body’s ability to absorb those nutrients.
What Is Biofortification?
Biofortification improves the nutritional quality of crops during their growth and development.
According to WHO, it can involve:
- Conventional plant breeding: Selecting and crossing plants with desirable nutritional traits.
- Agronomic practices: Improving nutrient availability through suitable cultivation practices.
- Modern biotechnology: Using relevant biological techniques to enhance crop characteristics.
Biofortification vs Food Fortification
| Basis | Biofortification | Food fortification |
|---|---|---|
| Stage | Nutrient improvement occurs in the crop during growth | Nutrients are added during food processing or preparation |
| Approach | Breeding, agronomic practices or biotechnology | Addition of selected vitamins or minerals |
| Example | Nutritionally improved crop varieties | Iodised salt |
| Delivery | Through consumption of the improved crop | Through consumption of the fortified food |
Prelims trap: A biofortified crop is not necessarily genetically modified. Biofortification can also be achieved through conventional breeding and agronomic practices.
How Can Biofortification Address Hidden Hunger?
Hidden hunger refers to deficiencies of essential vitamins and minerals, which can occur even when a person consumes sufficient calories.
Biofortification can improve the nutrient content of foods that people already eat regularly. It is therefore relevant to the shift from food security, focused on access to adequate food, towards nutrition security, which also requires dietary quality.
However, biofortified crops should complement dietary diversity, public-health services and other nutrition interventions. They cannot independently address every cause of malnutrition. WHO recognises biofortification as a nutrition-sensitive agricultural intervention.
How Does Kufri Jamunia Differ from Other Coloured Potatoes?
| Variety | Skin colour | Flesh colour | Key feature |
|---|---|---|---|
| Kufri Neelkanth | Dark purple to purple-black | Cream | Antioxidant-rich specialty table potato |
| Kufri Manik | Deep red | Yellow | Biofortified table potato with an improved nutritional profile |
| Kufri Jamunia | Dark purple | Purple | Purple-fleshed variety rich in anthocyanins |
ICAR’s description confirms that Kufri Neelkanth has cream flesh, despite its purple skin. This is a useful distinction for statement-based Prelims questions.
Exam note: Official publications differ on Kufri Manik’s release year: an ICAR compendium records 2020, while the recent PIB explainer states 2021. Its characteristics and developing institution are safer revision points than an unqualified release-year claim.
Why Is This Development Important for Himachal Pradesh?
1. Role of ICAR-CPRI, Shimla
The Central Potato Research Institute is located in Shimla, Himachal Pradesh. Kufri Jamunia illustrates the contribution of research institutions based in the state to agricultural development across India.
2. Research and Extension Opportunities
The development provides a useful example for HPAS answers on:
- Crop improvement and agricultural research.
- Production and distribution of quality planting material.
- Farmer training and field demonstrations.
- Links between research institutions, farmers and markets.
3. Potential for Value Addition
Specialty potatoes may create opportunities in differentiated food products and culinary markets. Realising these opportunities requires reliable supply, consumer acceptance and viable prices.
Important qualification: Development at Shimla does not mean that Kufri Jamunia is recommended for every hill region of Himachal Pradesh. Adoption should follow local trials and official agro-climatic recommendations.
What Challenges Could Limit Adoption?
- Availability of planting material: Farmers need access to healthy, authentic seed tubers.
- Consumer acceptance: Purple flesh may be unfamiliar to buyers accustomed to white or yellow potatoes.
- Market uncertainty: A specialty variety does not automatically command a profitable premium.
- Nutrient retention: Storage, cooking and processing can influence the final nutritional contribution.
- Regional suitability: Yield and quality depend on climate, soil, management and disease pressure.
Way Forward
- Strengthen seed multiplication: Ensure timely access to quality planting material.
- Expand field demonstrations: Compare performance under local farming conditions.
- Improve consumer awareness: Explain the variety’s characteristics without exaggerated health claims.
- Develop market linkages: Connect farmers and producer organisations with suitable buyers.
- Assess nutritional outcomes: Study nutrient retention, bioavailability and actual consumption.
- Promote dietary diversity: Position biofortified crops within a broader nutrition strategy.
Key Prelims Takeaways
- Kufri Jamunia → Biofortified purple-fleshed potato.
- Developed by → ICAR-CPRI, Shimla.
- Released → 2024.
- Recommended regions → Northern, Central and Eastern plains.
- Anthocyanins → Pigments associated with purple colour.
- Kufri Neelkanth → Purple skin, cream flesh.
- Biofortification ≠ necessarily genetic modification.
- A potato tuber is a modified underground stem, not a root.
Kufri Jamunia demonstrates how crop research can combine agronomic performance with improved nutritional quality. Its wider impact will depend on quality planting material, farmer adoption, consumer acceptance and evidence of nutritional benefits.
