  8. 8. Purpose of Biosafety Research Trials• To evaluate the performance of the GM events• To collect biosafety data needed to meet regulatory requirements for commercial release and• To produce material needed for food, feed and environment safety assessments
  9. 9. Confined Field Trial for Biosafety Testing• Confined field trial option employed for biosafety testing of GM crop• A confined field trial is a field experiment under terms and conditions that are intended to mitigate the establishment and spread of the plant
  10. 10. No Mateiral Goes Out of Trial Site • The confined field trial system is not intended to support other activities such as, • commercial seed multiplication or • No seed can be harvested from BRL trials • For seed production, a separate regulatory authorization needs to be obtained at a different site • Entire biological produce has to be destroyed after the data generation is completed
  11. 11. Types of Biosafety Trials for GM Crops• RCGM is the regulatory authority for Event Selection Trial (with the approval of GEAC)• Mandatory Trials: BRL I (2 years); BRL II (1 Year)• RCGM is the regulatory authority for Bioafety Research Level I (BRL I) trials (with the approval of GEAC)• GEAC is the regulatory authority for Biosafety Research Level II.(BRL II) trials (recommendation of RCGM)• Minimum off three years BRL trials are required for
  12. 12. Trial Size and Number of LocationsI. Biosafety Research Level I (BRL I)trials are limited in size to A. No more than 1 acre (0.4 ha) per trial site location and B. Cumulative total of 20 acres (8.1 ha) for all locationsfor each plant species/construct combination, per Applicant,per crop season. C. No more than two events (single or stacked) per trial, 2-3 genotypes per event D. Each event genotype should have its non-transgenic counterpart E. Appropriate checks (national and regional)
  13. 13. Trial Size and Number of LocationsBiosafety Research Level II trialsA. no more than 2.5 acres (1 ha) per trial site location andB. no more than eight (8) locations within India for each plant species/construct combination (e.g., one or more events originating from transformation of a plant species with the same genetic construct) per Applicant, per crop season
  14. 14. Composition of BRL 2 TrialsA. No more than two genotypes per GE event if more than one event was tried in the BRL I trial andB. If only one GE plant genotype was evaluated in the BRL I, the same composition with the same number of treatments as in BRL I need to be maintainedC. The selection of the GE plant genotype/genotypes should be strictly based on the performance evaluation conducted in the BRL I, approved for advancing to BRL II, by the regulatory body.D. The plot size should be a minimum of twice the size of the plot adopted in the BRL I

  23. 23. Compliance RecordsRecords of all confined field trials to be maintained by the PermittedParty to be made available to RCGM/GEAC including •pre- and post-harvest site monitoring •activities related to trial site compliance (including subcontracts) •cleaning of equipment •transportation •disposition and •storage of all surplus and harvested seed and plant materialMandatory recording formats for Confined Field Trials of GeneticallyEngineered Crops : Transport, Storage, Management, Harvest orTermination and Post Harvest Management and can bedownloaded from
  24. 24. Mandatory Information Submissions by ApplicantI. Planting Information Submission:RCGM/GEAC shall be informed in writing within 7 working daysof planting at a trial site:•Record of Planting shall be submitted and must reference the confined trial permit number and document, •document the amount of material planted •the planting date •the transportation of plant material to the trial site •the cleaning of any equipment used during planting, and •the disposition of any surplus plant material remaining after planting•If it was not provided with the application, this notification mustalso include a detailed map of the trial site along with experimentalfield layout plan
  25. 25. II. Harvest Information Submission:A Record of Harvest/Termination shall be prepared for each confinedfield trial site and shall document•the date and method of harvest,•the amount of harvested material,•the disposition of any harvested materials,•the cleaning of any equipment used during harvest, and•the method of destruction of any residual plant material on the trial site. This record must be verified and signed by a member of theMonitoring Agency or any nominee of RCGM /GEAC /SBCC /DLC/SAU authorized by RCGM/GEAC during the conduct of a trial siteinspection during harvest, or within 15 days of the completion of harvest
  26. 26. III. Accidental Release Information :The Permitted Party shall notify RCGM/GEAC immediately upondiscovery by telephone but positively within 24 hours in writing ofany incident involving an accidental or unauthorized escape like, •Spillage, •Theft or encroachment by unauthorized persons, •vandalization etc. of regulated GE plant material during transportation, storage within a contained facility, or during any other activity associated with the conduct of a confined field trialAny breach of the authorized terms and conditions ofreproductive isolation shall be considered an accidental release andsubject to risk assessment and management if any at the cost of theapplicant or Permitted Party
  27. 27. Other Submissions :In the event that the plants undergoing confined field trialtesting exhibit any characteristics substantially different from•those known for the host plant species,• anticipated and listed in the application,•or suffers any unusual occurrence,the Permitted Party shall notify RCGM/GEAC in writingwithin five (5) days of such observations
  28. 28. Reproductive Isolation of Confined Field Trials•To prevent their establishment and spread within theenvironment, regulated GM plants within a confined trialmust be reproductively isolated from sexually compatibleplant species in proximity to the trial site, and any progenyplants that arise on the trial site after completion of the trialmust be eliminated•It is the responsibility of the Permitted Party to ensure thatthe conditions for reproductive isolation of all trial plants aremet during growing season and the post-harvest period
  29. 29. Spatial Isolation•The primary means of achieving reproductive isolation is through theimposition of a spatial isolation distance between the trial plants andany neighbouring sexually compatible plants•Minimum spatial isolation distances vary depending on thereproductive biology of the plant species•The spatial isolation area defined by the isolation distance must becontinuous and completely surround the confined trial site•Any prohibited plants found growing within the isolation area shall beremoved prior to flowering, otherwise, a breach of reproductiveisolation shall be deemed to have occurred•In the event of any breach of reproductive isolation, the post-harvestland use restrictions and requirements for post-harvest monitoringshall apply to both the trial area and the surrounding isolation area
  30. 30. Alternative Methods of Reproductive IsolationApplicants should refer to the crop-specific RCGM/GEAC SOPs todetermine if alternative methods of reproductive isolation will bepermitted:1. Removal of floral parts before pollen maturity2. Bagging of flowers/tassels to prevent open pollination3. Termination of the trial prior to flowering4. Temporal isolation of pollination (i.e., planting earlier or later thanany nearby sexually compatible plants so that flowering isasynchronous)5. Planting of border rows of non-regulated plants of similar variety asthe trial plants to act as a pollen trap (This is only applicable to insect-pollinated crops and only when experimental studies havedemonstrated that pollen traps are as effective as spatial isolation forthe purpose of reproductively isolating a field trial site)
  31. 31. Disposition of Material from Confined Field Trial•No harvested material or byproduct from a confined field trial may beused as human food or livestock feed•Seed or other plant material harvested from confined trials (includingborder rows) that has not been previously authorized by RCGM/GEACto be retained for future research work, must be disposed off by amethod approved by RCGM/GEAC (e.g., dry heat, steam heat,incineration, deep burial, chemical treatment, or crushing or burying onthe trial site)•Composting is not an acceptable method for the disposal of plantmaterial especially in open pit with any organic animal waste•Progeny from any confined field trial cannot be retained for futureplanting without prior written authorization from RCGM/GEAC, andthis must be specifically requested in the field trial application
  32. 32. Post-Harvest Land Use Restrictions and Post-Harvest MonitoringIt is also necessary to prevent the establishment of any progeny plantsat the field trial site during subsequent growing season. Therefore, apost-harvest period for various plant species on a case-by-case basisis established and requires following precautions to be implemented:1. The area under restriction must be monitored during the post-harvest period to ensure that any prohibited plants (volunteers or sexually compatible species) are destroyed prior to flowering2. No plants of the same or a sexually compatible species may be planted in the restricted area during the post-harvest period3. Land use of the restricted area must be compatible with requirements for monitoring and removal of prohibited plants. No plants that could interfere with monitoring for prohibited plants can be plantedThe restricted area is normally limited to the area of the trial site, anddoes not include the surrounding isolation area unless a breach ofreproductive isolation occurred
  33. 33. Field Trial Report•The Permitted Party shall submit a field trial report toRCGM/GEAC within 3 months after termination/harvest of a confined field trial•The field trial report must summarize the completed trial,including methods, observations, data and analysis of anyeffects of the trial plants on other plants, non-targetorganisms, or the environment
  34. 34. Detailed information to be made available to theMonitoring Agency/ies* As per designed proforma* As truthfully as can be perceived* Any item not included in the proforma but the experimenter perceives as a potentially unsafe trait/effect
  35. 35. Proposed Combined Trials for Biosafety and Productivity• BRL 1 (I & II Year) can be aligned with field experimentation in line with IVT 1 and AVT 1• BRL 2 (I year) can be aligned with field experimentation in line with AVT II along with ancillary data sets generation (Agronomy, quality, pathology, physiology, etc.)• The BRL and AICCIP trial combine as “ IVT/AVT-GM” Trials following EPA 1986 and SA 1966
