  • IMI-Resistant Mustard Hybrids

    Why in the news?

    India is set to begin large-scale cultivation of imidazolinone-resistant (IMI-resistant) mustard hybrids during the 2026-27 rabi season to tackle the parasitic weed Orobanche (Phelipanche), which significantly reduces mustard yields.

    Key Highlights

    • Mustard is a major oilseed crop in India.
    • India imported around 16 million tonnes of edible oil and Worth nearly ₹1.6 lakh crore in 2024-25.
    • The new hybrids are resistant to IMI herbicides
    • Main target Orobanche/Phelipanche, a root parasitic weed.

    What is Orobanche?

    https://images.openai.com/static-rsc-4/Qei5WJuL-Rr_xTIzlCInNirTBQpRVL3O34CGG6B68RBWV0IAE1OJC19nfEHxPF8pd4N3UBIyCrDEXg4K_8VjNBKQchGiadQ9D4C-Nh_wdl2OaRZ_ZT9no0h2Jadoxh9AhOsPBZJHloSRD_kA2CRmo_W98rssDji6_lHfc2ADRkM4lB-50F4ZX-LttuPjq6Wt?purpose=fullsize
    • A parasitic weed that attaches to mustard roots. Draws water and nutrients from the host plant
    • Causes major yield losses in mustard cultivation.
    • Difficult to remove manually because it grows below the soil surface.

    What are IMI-Resistant Mustard Hybrids?

    • These are mustard varieties resistant to imidazolinone herbicides.
    • Developed Through: Mutation Breeding. Not a genetically modified (GM) crop. Scientists select and preserve naturally occurring mutations.

    Scientific Basis

    • The resistance is linked to changes in the Acetolactate Synthase (ALS) enzyme
    • Normally, IMI herbicides inhibit the ALS enzyme. The plant dies.

    In resistant hybrids:

    • A DNA mutation changes ALS structure.
    • Herbicide cannot inhibit the enzyme.
    • Crop survives while weeds die.

    Advantages

    • Effective control of Orobanche.
    • Reduces labour requirement for manual weeding.
    • Helps improve mustard productivity.
    • Supports reduction in edible oil imports.
    • Useful in labour-scarce periods during the rabi season.

    [2018] 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 hybridise.
    3. GM mustard has been developed jointly by the IARI and Punjab Agricultural University.
