Question map
With reference to the Genetically Modified mustard (GM mustard) developed in India, consider the following statements : 1. GM mustard has the genes of a soil bacterium that give the plant the property of pest-resistance to a wide variety of pests. 2. GM mustard has the genes that allow the plant cross-pollination and hybridization. 3. GM mustard has been developed jointly by the IARI and Punjab Agricultural University. Which of the statements given above is/are correct ?
Explanation
The correct answer is option B (Statement 2 only).
**Statement 1 is incorrect:** GM mustard has the genes of a soil bacterium that give the plant the property of pest-resistance to a wide variety of pests[1] is mentioned in one source, but this contradicts the actual purpose of GM mustard. The technology was developed for hybrid seed production through inducing male sterility and fertility restoration system for hybrid seed production (Barnase and barstar gene from bacterium)[2], not for pest resistance.
**Statement 2 is correct:** The bar gene was introduced to overcome this problem by conferring resistance to the weedicide, phosphinothricin. This enabled the breeders to spray the weedicide to remove plants that did not have male sterility and retain only those plants with the sterility gene; this would produce 100% pure seeds.[3] The genes enable stable male sterility under all conditions, and the subsequent restoration of fertility to produce hybrids with pure seeds[4], which facilitates cross-pollination and hybridization.
**Statement 3 is incorrect:** The much-delayed genetically modified mustard developed by the University of Delhi[5] shows it was developed by Delhi University, not jointly by IARI and PAU. While trials have been approved at two locations–Punjab Agriculture University (PAU), Ludhiana and Indian Agricultural Research Institute (IARI), New Delhi[6], conducting trials is different from developing the technology.

PROVENANCE & STUDY PATTERN
Full viewThis is a classic 'Depth over Breadth' question. Merely knowing 'GM Mustard is in news' fails here; you needed the specific functional mechanism (hybridization vs pest resistance) and the developer identity. It punishes aspirants who conflate all GM crops with 'Bt' (pest resistance).
This question can be broken into the following sub-statements. Tap a statement sentence to jump into its detailed analysis.
- Statement 1: Does the Genetically Modified mustard (GM mustard) developed in India contain genes from a soil bacterium that confer pest resistance to a wide variety of pests?
- Statement 2: Does the Genetically Modified mustard (GM mustard) developed in India contain genes that enable cross-pollination and hybridization (e.g., male-sterility and fertility-restorer genes)?
- Statement 3: Was the Genetically Modified mustard (GM mustard) developed in India developed jointly by the Indian Agricultural Research Institute (IARI) and Punjab Agricultural University (PAU)?
- Directly states that GM mustard has genes from a soil bacterium.
- Specifically links those genes to conferring pest-resistance to a wide variety of pests.
- Explains that crystal protein (Cry) genes from bacteria are used to confer pest-resistance in plants.
- Provides the general mechanism by which bacterium-derived genes can give pest-resistant traits, supporting the claim about GM crops.
Gives the general rule that GM plants receive foreign genes (transgenes) from other organisms when modified.
A student could use this rule to ask whether the specific DMH‑11 description lists a transgene and from which organism it was sourced (e.g., check GEAC/ICAR documents).
States that one purpose of GM crops is to provide resistance to bacteria, viruses and other damaging agents, showing pest‑resistance is a common engineered trait.
A student could therefore look for trait summaries of DMH‑11 to see if pest‑resistance is the engineered trait and how it is achieved.
Notes that GEAC reviewed and recommended DMH‑11 (GM mustard) for environmental release and required studies on pollinators — indicating official dossiers exist describing DMH‑11 traits.
A student could consult the GEAC recommendation/report referenced here to find technical details about the inserted genes and their source.
Mentions prior GEAC clearances and the regulatory process (e.g., Bt brinjal, Bt cotton) indicating that GM crops with pest‑resistance traits have been evaluated in India.
Using this pattern, a student could compare the documented trait sources in previously evaluated GM crops to the DMH‑11 dossier to see if a soil bacterium gene was used.
Discusses specific environmental/management consequences of particular engineered traits (herbicide resistance) showing that different transgenes confer distinct resistances.
A student could use this example to reason that DMH‑11’s documented trait will specify whether it is herbicide resistance, pest resistance, or another trait, and then verify gene origin.
- Explicitly states the bar gene was introduced to enable selection of plants with the male-sterility trait.
- Links this genetic approach to breeders at the University of Delhi who applied the technology, implying the Indian GM mustard uses such genes.
- Names the specific genetic system (barnase and barstar) used to induce male sterility and restore fertility for hybrid seed production.
- Shows that GM approaches commonly incorporate dedicated male-sterility and fertility-restorer genes.
- States GM technology can induce stable male sterility and subsequently restore fertility to produce hybrids with pure seeds.
- Provides broader context that GM systems are used to enable hybridisation in self-pollinating crops like mustard.
Defines GM organisms as plants with foreign genes inserted, establishing that specific reproductive-trait genes (like male-sterility/restorer) can in principle be introduced by genetic engineering.
A student could use this rule to infer that if male-sterility or restorer genes exist, they could be introduced into mustard via transgenic methods and then check specific trait descriptions or approvals for DMH-11.
Notes that GM mustard 'can contaminate other fields through cross-pollination', indicating concern about gene flow from GM mustard to non-GM crops.
Combine this with basic knowledge that male-sterility/restorer systems promote hybrid seed production and could increase cross-pollination potential, then examine DMH-11 breeding notes or biosafety reviews for such systems.
Mentions DMH-11 specifically and that regulators required field studies on effects on pollinators (honeybees), linking this GM variety to pollination-related environmental assessment.
A student could take this as a cue to look for whether DMH-11's breeding strategy involves traits that alter pollination biology (e.g., male-sterility) in regulatory dossiers or GEAC reports.
Explains that GEAC is the apex regulator for GM crops in India, implying that trait-level details (including reproductive trait genes) would be part of regulatory assessment.
Use this to justify searching GEAC minutes/reports or regulatory submissions for DMH-11 to find whether male-sterility/restorer genes were included.
Contains an explicit textbook assertion that 'GM mustard has the genes that allow the plant cross-pollination and hybridization', showing that at least some educational sources assert reproductive-trait modification.
Treat this as a reported claim to be verified: a student could cross-check primary regulatory documents or scientific descriptions of DMH-11 to confirm whether the claim refers to specific male-sterility/restorer genes.
- Directly states which institution developed the GM mustard, attributing development to the University of Delhi.
- This contradicts the claim that IARI and PAU jointly developed the GM mustard.
- Shows that PAU and IARI were sites for field trials of GM mustard, indicating involvement in testing rather than primary development.
- Supports distinction between conducting trials at PAU/IARI and being the developer of the crop.
Identifies the GM variety as DMH‑11 (Dhara Mustard Hybrid) and notes GEAC/ICAR involvement in follow-up field studies, linking the variety to national regulatory and research bodies.
A student could use this to look specifically for developer attribution for DMH‑11 (Dhara) in ICAR/IARI or state university records to see if IARI+PAU are named developers.
States DMH‑11 (GM mustard) was cleared by GEAC for field trials in 2016, highlighting the formal project name and timeline for the crop's development.
Use the DMH‑11 name and 2016 trial clearance date to search records, publications, or press releases from IARI, PAU or collaborating institutions around that period to check joint-development claims.
Explains ICAR is the coordinating agency for agricultural research and that agricultural universities conduct teaching and research, establishing the typical institutional relationships in crop development.
Apply this pattern to expect ICAR/ICAR‑linked institutes (like IARI) and state agricultural universities (like PAU) to appear in collaborative project documentation for a new crop variety.
Describes GEAC as the apex regulator for GM crops under the Environment Protection Act, indicating regulatory filings (GEAC submissions) would name developers/ applicants.
Check GEAC submission documents or recommendations for DMH‑11 to see which institution(s) are listed as developers or applicants (IARI, PAU, private partner etc.).
Discusses broader issues and impacts of introducing GM mustard (herbicide use, pollinators), implying extensive studies and stakeholder documentation likely exist naming technical developers and collaborators.
Search the technical/environmental assessment reports and stakeholder submissions referenced in debate over GM mustard for explicit attribution of development to specific institutes.

The 'Bar' gene in DMH-11 confers resistance to the herbicide Glufosinate (brand name Basta). While the government markets it as a 'Hybridization' technology, activists oppose it as a 'Backdoor Herbicide Tolerant' crop. This dual-nature is a prime candidate for future statements.
Apply the 'Signature Tech' filter. 'Pest resistance' is the signature of 'Bt' crops (Bacillus thuringiensis). DMH-11 was famous for being a 'Hybrid' technology. If Statement 1 says 'Pest Resistance', it contradicts the fundamental identity of the crop. Eliminate 1. Also, 'Jointly developed by X and Y' is a high-probability fabrication template used by UPSC to make false statements sound authoritative.
Connects to GS-3 Economy (Edible Oil Mission): India imports ~60% of its edible oil. DMH-11 is pitched as a solution to reduce the Current Account Deficit by breaking the yield barrier in domestic mustard via heterosis (hybrid vigor).
