Recognition & Accolades

Achievements & Honours 20 Honours

Recognised as the Best Researcher of Assam Agricultural University, 2017 by the University authority.

Recognised as the Best Center, AICRIP on Rice during 2023 (based on five years performance 2017-2022).

Developed submergence tolerant rice variety, Ranjit Sub-1, and Bahadur Sub-1. These Sub1 Introgressed varieties were released and notified by the Central Seed Committee, Government of India during 2018. The Ranjit Sub-1 is the first variety from Assam Agricultural University developed by using biotechnological tools and subsequently notified by the Government of India. The variety accepted by the farmers of Assam and during Kharif, 2022 the variety spread to more than 4 lakh hectare area

Developed medium duration high yielding rice variety, Numali. The variety out yielded the check varieties Satyaranjan and Basundhara by 20 percent. The variety was released and notified by the Central Seed Committee, Government of India during 2020

Involved in the development of rice variety Gitesh having the staggering ability. The variety was released and notified by the Central Seed Committee, Government of India during 2017

Developed a high-yielding mid-duration variety TTB 404 (Shraboni); varieties for waterlogged situations; Dhansiri, Diphalu, and Chakra. These varieties are recommended by the Assam Agricultural University for cultivation in Assam

Identified two hybrid rice varieties, Arize 6129 and PAC 837 boro season of Assam. Based on the testing results-on station, multi-locational trial, and on-farm trial, these two varieties have been recommended by the Technical Committee, Assam Agricultural University for cultivation during the Boro season of Assam

Evaluated the Sub1 introgressed lines such as Swarna Sub-1, Samba Mahsuri Sub-1, IR64 Sub-1, BR11 Sub-1, CR1009 Sub-1, and some other climate-resilient rice varieties through participatory varietal selection mode in different districts of Assam in the International Project, “Stress tolerant rice for the poor farmers of Africa and South Asia” funded by Bill & Melinda Gates Foundation. Based on the testing results; Swarna Sub 1, BR-11 Sub1, Dhansiri, Diphalu, Manah, and Chakra Sali have been recommended for flood-affected, waterlogged areas of Assam

Have been working in the International Projects RESILIENCE, AGGRi Alliance, and Global Rice Array as the contact person. Also worked in an International Project ‘Assessing the consequences of severe flooding on men and women in ensuring food security and sustaining livelihoods: a case study in rice-based farming’, funded by International Rice Research Institute, Philippines, and in the project STRASA funded by the Bill & Melinda Gates Foundation

Established a Molecular Marker Laboratory at Regional Agricultural Research Laboratory. The necessary molecular marker works for introgressing the Sub1 gene have been carried out in this laboratory and developed and released two varieties. Further, introgression of bacterial blight, blast, and drought resistance is going on.

Mentored five Ph.D. students and twelve M.Sc. Students. Evaluated Ph.D. thesis of Tamil Nadu Agricultural University, Coimbatore

Received Certificate of Appreciation from Vice Chancellor, AAU for developing rice varieties Labanya and Dholi during 15th August 202

Developed medium duration high yielding submergence tolerant rice variety, Dholi. This Sub1 introgressed line is in Ranjit background. The variety out yielded the check varieties by 15 percent. The variety was released and notified by the Central Seed Committee, Government of India during 2022

Associated with development of HYV Surma Dhan . The variety has duration advantage over Ranjit. The variety was released and notified by the Central Seed Committee, Government of India during 2022

Developed High yielding Aromatic Purple Rice variety Labanya, sent to the PPVFRA for registration during 2021. Further, the rice of the variety will be marketed through e-commerce platform, Amazon. This is the first product of AAU to be available online. Moreover, EoI has already been floated by the university authority to give the the marketing right of this variety to Private organisations.
