    Question: Which is a genetically modified crop?

    Options:

    Bt- Brinjal
    Bt-cotton
    Golden rice
    All of the above

    🔑Key Points:    
    Genetically modified crop –
    These are seeds whose genetic material has been scientifically modified.Such crops are genetically modified in their design.
    By doing this, the production of crops increases, and the quantity of essential elements increases.
    Bt- Brinjal –
    It was developed by the 'Maharashtra Hybrid Seeds Company (Mahyco). 
    Bt brinjal is the first food crop under evaluation for commercial release in India. ​
    Bt-cotton –
    Bt cotton is the only permitted GM crop in India.
    In which the soil is obtained by hybridization of two foreign genes with the bacterium "Bacillus thuringiensis" (BT).
    These genes help the cotton crop secrete a toxic protein to protect it from an insect called the common pink bollworm.​
    Golden rice –
    It is a variety of paddy made with GM technology.
    It has a sufficient amount of vitamin-A, and its color is like turmeric.

    🔴Additional Information:
    The Genetic Engineering Appraisal Committee (GEAC) is an apex regulatory body on genetically modified plants.
    The Modi government has approved the field trials of indigenous Bt brinjal varieties ‘Janak’ and ‘BSS-793’. 
    The 'International Rice Research Institute' is located in the Philippines. 
    From 2002, the use of Bt cotton seed was introduced as genetically modified crops in India (GM).
