Developed by the Indira Gandhi Agriculture University (IGAU), Raipur, Central Variety Release Committee has released three new varieties of rice for Chhattisgarh.
These three varieties are named ‘Trombay Chhattisgarh Dubraj Mutant-1, Chhattisgarh Devbhog and Chhattisgarh Zinc Rice-2. These varieties were notified for the State of Chhattisgarh taking in view the suitability, high production capacity, quality, nutrient value, resilience to insects and diseases, capacity to survive hostile weather conditions, medicine and other characteristics at Indian Institute of Rice Research, Hyderabad, recently. Chhattisgarh State Seeds Sub-Committee had already approved these varieties.


Salient features of these varieties are as follows: Trombay Chhattisgarh Dubraj Mutant-1 is the first variety developed using Gama Radiation induced mutation with the assistance of Bhabha Atomic Research Centre, Mumbai. It’s a medium dwarf variety which qualitatively alike Dubraj. It was developed considering the popularity of the Dubraj. It grows up to 90 to 95 centimeters derived from the local Dubraj which grows around 135 to 150 cm, which affects production and quality due to lodging. Its fertilising capacity is also quite good, which is found at 47 quintals per hectare at national-level. Its yield is quite high even with less fertilizer. The variety has been recommended for irrigated state.


Second variety of Chhattisgarh Devbhog has been developed through the process of selection, in which seeds of Swarna and Jirasankar varieties were selected as Germinatives for cross germination. Its yield is around 45 to 50 quintals per hectare within 135 to 140 days. This variety has a rice producing capacity of 67.6 per cent. This has been recommended for irrigated state in Chhattisgarh.


Chhattisgarh Zinc Rice-2 has been developed with the bio-certified technique. With 22-24 ppm Zinc content, this is a premium variety. It’s a small grain variety, which is tasty to eat. It has been found 42 quintal per hectare yield, higher than other nutri-rich varieties at national level. It also has higher rice bran oil content than other varieties. High content of zinc makes it nutritious and makes it suitable in controlling diarrhoea in younger children. It was developed by adopting the pedigree after the cross germination of IR-68144-B-18-2-1-1 and PKV HMT.
