REVISED GUIDELINES

  • ICAR-IIRR has an exemplary high-grade scientific environment and standards for the budding researchers. ICAR-IIRR has well established field facilities, sophisticated instrumentation facilities for all the sections viz. crop improvement, crop production, crop protection, transfer of technology, agricultural engineering.

Field facilities

ICAR-IIRR has well designated field facilities lowland and upland according to rice ecosystems. ICAR-IIRR has nutrient gradient field plots i.e. low nitrogen and recommended nitrogen fields plots, low phosphorus and recommended phosphorus. The field plots are maintained without application of the nutrient for which the screening needs to be done.

Guidelines for student internship programs at IIRR (M.Sc/Ph D/others)

  • In case of students, irrespective of PhD/MSc/Intern/Trainee, whether short term or long term, a request letter from the concerned university/institute should always be sent to the Director, IIRR, instead of the individual scientists. No individual requests should be entertained by the scientists from any agency/Institute. The Academic committee will process all the applications and get the final approval from the Director, IIRR before admission.
  • The student who is admitted to undertake MSc/PhD research work should submit a copy of ‘Outline of Research Work’ (ORW) before starting the work in the department concerned.
  • Students pursuing Ph.D. degree need to give a seminar on their research work prior to submission of their thesis.
  • Applications for Research Fellowships/ SERB/ INSPIRE Etc. should be submitted through the Head of the section to the Academic committee/ PMEC for approval of the Director.
  • Approval of DARE-ICAR/ Council is necessary for mentoring Foreign Students irrespective of their sponsorship and funding. Their applications should be submitted 3 months in advance for obtaining approval from DARE-ICAR.
  • As per the ICAR guidelines the IP rights of the admitted students rest with IIRR and so the students will have to submit their lab/field data books/workbooks having raw data/methods/ procedures to their respective supervisors. As per the guidelines, due credit should be given to the concerned students in publications/reports etc. Any dispute arising out of the students research work will be resolved as per the ICAR Guidelines.
  • Students should submit a copy of final thesis (soft and hard copy) to the IIRR, Library through the supervisor with intimation to PMEC/Academic committee after finishing final viva.
  • A temporary Identity Card signed by the competent authority shall be issued to students admitted to do their research work at IIRR Laboratories.
  • As per the ICAR guidelines, the students interested in pursuing their graduate/post graduate/others research work leading to dissertation/thesis/training/internship outside the NARS should pay the prescribed fees to IIRR after approval their application by the Director, IIRR as mentioned below:

            1. M. Sc /M.Tech Dissertation work      : Rs. 30,000/-

            2. Ph. D thesis work                           :  Rs. 30,000/- per semester

DRR Dhan 48

DRR Dhan 48-Zinc Rich Biofortied Rice Variety

Technical details
DRR Dhan 48 (IET 24555) is a biofortified high zinc variety developed from the cross RPBio226*1/CSR27 following backcross and pedigree selection breeding released in the year 2018. The variety is similar to variety BPT 5204 popularly known as ‘Samba Mahsuri’ in most of the characters. This variety contains high zinc content of 22 ppm in polished rice and 27 ppm in brown rice which is higher than the checks BPT 5204, IR64, Kalanamak. It also out yielded the checks BPT 5204, IR64 which is a national check, Kalanamak and chitimuthyalu in the states released. The variety is distinguishable through morphological features like semi dwarf and strong culm which confers resistance to lodging, late senescence, erect and wide flag leaf which help in improving the photosynthetic ability which again helps in increasing the yield. compact heavy and completely exerted panicles and possesses desirable grain type of medium slender grains. The variety is late with duration of 135 – 140 days (Seed to seed).

Empirical evidences:

In the trials in AICRIP trials at various locations in Andhra Pradesh, Karnataka, Tamil Nadu and Kerala DRR Dhan 48 established the yield advantage of 21.8, 8.9, 8.2 and 17.7 % higher than the best check respectively along with 22 ppm of zinc in polished rice and 27 ppm in brown rice.

  • It has Xa21+xa13+xa5 genes introgressed for bacterial leaf blight (BLB) and hence is resistant to BB. It has also showed moderate resistance to RTD, sheath rot, neck blast and brown spot.
  • It has got good quality parameters like High milling recovery (69.4%), Head rice recovery (60.9%), medium slender grain. It also possesses good cooking quality with intermediate amylose content (24%), alkali spreading value (7.0) and GC (28 mm) with very occasionally chalky.
  • The variety is recommended for cultivation in southern states like Telangana, Andhra Pradesh, Karnataka, Tamilnadu and Kerala.

Success story of DRR Dhan 48-Performance in farmer’s field
Sangi Nagaiah/Tummala Murali of Aroor village, Valigonda mandal, Yadadri Bhuvanagiri District of Telangana cultivated DRR Dhan 48 during kharif 2020 in an acre under the technical guidance of IIRR Scientists. Farmers appreciated the traits of DRR Dhan 48 in terms of it desirable plant height (slightly shorter than BPT 5204), resistance to bacterial blight despite not taking up plant protection measures and grain type akin to BPT 5204 and appreciated high (15-18) productive tillers per plant. Seed samples collected from farmer’s field as well as from IIRR, Rajendranagar farm were used for zinc estimation at International Rice Research Institute South Asia Hub (IRRISAH), ICRISAT, Hyderabad. The average zinc content in seed samples collected in farmer’s field ranged from 25.2 to 27.4 and 22.2 to 23.3 ppm in brown and polished rice respectively while in seed samples of IIRR farm ranged from 24.9 to 27.1 and 21.0 to 21.3 ppm in brown and polished rice respectively. Scientists from IIRR visited the farm at regular intervals during reproductive stage and performed roughing.

Impressed by the high yield and being aware of nutritional importance, Tummala Murali increased the area under cultivation up to 4 acres during rabi 2021. Scientists from IIRR closely monitored the fields and provided technical guidance from time to time. IIRR Scientists, research scholars and technical assistants visited the field at regular intervals to remove offtypes and mixtures which helped the farmer to maintain seed purity. Tummali Murali produced about 8 tonnes and expressed immense satisfaction. About 6300 kg of seed produced from his field was bought back by IIRR under SC-SP project and distributed to 210 identified beneficiaries for cultivation during kharif 2021. Tummali Murali is further extending cultivation to 8 acres during kharif 2021 and seeing his success story, many farmers from their village and neighbouring villages bought seed from Tummala Murali and will be taking up cultivation of DRR Dhan 48 during kharif 2021.

 

 

DRR Dhan 48 in farmer’s field during rabi 2021

 
   

 


DRR Dhan 48 is a biofortified high yielding nutritionally rich with zinc along with desirable grain characteristics like medium slender grain type and good cooking quality which is preferred by almost all the southern states like Telangana, Andhra Pradesh, Karnataka and Tamil Nadu.Practical utility/ Scalability:

  • Biofortification provides a feasible means of reaching malnourished rural populations who may have limited access to diverse diets, supplements, and commercially fortified foods. The variety is fortified with high zinc, it is estimated that it possesses 27 ppm in brown rice and 22 ppm in polished rice, which will help in curing ‘hidden hunger’ malnourishment in the poor people.
  • If this variety is multiplied in large scale and final polished rice is distributed through Public distribution system, it will reach the poor and malnourished people easily.
  • Using the tag of high zinc on the package would fetch more price in supermarkets thereby increasing the farmers income.
