New jackfruit varieties Siddu and Shankara redefine nutrition and market appeal

Two new jackfruit varieties, Siddu and Shankara, have been developed by the ICAR-Indian Institute of Horticultural Research (IIHR). These varieties stand out for their rich nutritional content and striking coppery red colour. Their commercial potential is already drawing interest from health-conscious and premium markets.

Jackfruit has long been a staple in rural Indian diets, valued for its sweet flakes and resilience in tough growing conditions. To rediscover its potential, ICAR-IIHR conducted surveys across Southern Karnataka. Researchers collected 128 samples, narrowed them down to 42, and finally selected Siddu and Shankara as the most promising varieties.

Both varieties are hardy and adaptable to tropical and subtropical climates. Siddu trees can produce up to 450 fruits a year, with an estimated yield of 1,098 kg per tree. The fruit weighs around 2.44 kg, contains 25 to 30 bulbs, and has high soluble solids (31 degrees Brix). It is also packed with nutrients: 4.43 mg of carotenoids, 1.12 mg of lycopene, 6.48 mg of vitamin C, and 31.76 mg of phenolics per 100 g. Shankara jackfruit, meanwhile, yields fruits of 2 to 5 kg, each with about 60 sweet, crisp, and aromatic flakes. Its nutritional profile is even stronger, containing 5.83 mg of carotenoids and 2.26 mg of lycopene per 100 g. The distinctive coppery red colour of both varieties gives them an advantage in premium and organic markets. ICAR-IIHR’s commercialisation model ensures that 75% of sapling sales revenue goes directly to farmers. The remaining 25% funds further research and extension work. This approach supports rural livelihoods while promoting sustainable farming practices. The success of these varieties in Tumkur highlights how native biodiversity can provide economic opportunities, community pride, and long-term sustainability for rural areas.

Siddu and Shankara jackfruits are now positioned as functional foods with strong market potential. Their high nutrient content and unique colour appeal to health-focused and premium buyers. The revenue-sharing model also ensures farmers benefit directly from their cultivation.
