 MESSAGE  by  DIRECTOR(A)

 

 

  

I heartily welcome you to DRR web site. The year 2013-14 witnessed record rice production of 106.19 million tonnes mainly due to timely onset of south-west monsoon and its reasonable good distribution across the country notwithstanding three consecutive cyclones (Phailin, Helen and Lehar) in the eastern region. Another notable feature was the country continued to be no. 1 rice exporter in the world since 2011, earning the highest foreign exchange of Rs. 33,858 crores through exports.

 

During the year, Directorate continued to play a significant role on research front with the release of eight hybrids and eighteen varieties by the Central and State Variety Release Committees. The breeder seed production accounted 555 tonnes of 220 varieties produced as per DAC indent. Our Directorate developed three varieties viz., IET 22598 (RP 5213-69-13-3-4-1-2-B), a high yielding mid-early duration variety; IET 22836 (RP 5208-3-IR87707-445-B-B-B), which is IR 64 NIL introgressed with two yield QTLs doing well under moderate drought and IET 22729 (RP 5311-PR 26703-3B-PJ7), an INGER culture promising in aerobic trials. Significant research achievements include identification of resistance elite lines against BPH and WBPH and basmati pyramided lines resistant to bacterial blight; several lines promising for nitrogen use efficiency and low phosphorous conditions. The complete genome sequence of RTSV isolate from southern India was successfully deciphered and deposited in the NCBI database. New varieties, hybrids and several proven crop production and protection technologies were demonstrated through 485 Front Line Demonstrations covering 15 states. As a part of commercialization endeavour with the private sector for upscaling of technologies, DRR signed four MoAs for DRRH-2 and one MoA for DRRH-3 during 2013-14.

Six new externally funded projects with a total budget of Rs. 1.76 crores were approved during the year. It is also heartening to note that the Directorate is going to lead the Consortia Research Platform on ‘Biofortification in selected crops for nutritional security’ during the XII Plan period.

The performance of DRR scientists has been exemplary and some of our scientists conferred the prestigious Hari Om Ashram Award for team research as well as individual awards. Over 60 research papers were published in high impact journals and several papers and posters were presented in national and international symposia. One scientist was deputed abroad for advanced training. Academic activity encompassed completion of ten research projects by M.Sc. students.

 

DRR will continue its efforts towards striving for excellence in rice research and coordination.  The staff members are also looking forward with great expectations to celebrate the forth coming event in 2015, the AICRIP Golden Jubilee year.
