Abstract

Sweet potato (Ipomoea batatas L.) is traditional food and super food for its calorie and vitamins contents as well as for easy availability among small, marginal farming communities. Sweet potato breeders of ICAR-CTCRI were working on improvement of sweet potato. The breeders have developed spectrum of coloured flesh sweet potato in orange containing beta carotene (10-16mg/100g) and purple containing anthocyanine (60-100mg/100g). Mythologically, different colours of rainbow signify power or positive energy. Among various coloured flesh sweet potato Bhu Sona and Bhu Krishna are gaining momentum in nutritional programme of the country. Besides, these varieties can perform well in hilly backward and coastal areas. Breeders also raised varied spectrum of coloured breeding lines having more nutrients and starch (>18%) with minimum weevil infestation (0-10%) for future programme. A special programme of intervention for eight tribal dominated districts, Odisha was undertaken for betterment of disadvantageous farmers through a RKVY programme. Further, ICAR-CTCRI distributed those rainbow coloured sweet potato in other backward areas of the country through various programme. Development of spectrum of coloured sweet potato satisfy disruptive innovation matrix. Those can be used primarily for wellness of disadvantageous farming communities. For their wellness, hunger-malnourished -vulnerable areas of the country need to be prioritized with holistic system based approach. These coloured flesh sweet potato can also be used for various processed products.
