New genetic tools are breathing fresh life into India’s staple crops
As new tools like apomixis become more widely available and private companies start investing more in Indian seeds, it is as important to think about how our system will adapt to these changes as it is to invest in fundamental research in plant genetics, physiology, development and host-pathogen interactions

Context
The article highlights the urgent need to revitalize fundamental plant science research in India to secure future food security, particularly for staple crops like rice and wheat. It argues that the anti-GMO (Genetically Modified Organism) movement has deterred students from pursuing plant biology, hindering the development of crops resilient to current environmental and agricultural challenges.
UPSC Perspectives
Economic
The economic lens focuses on the foundational role of agriculture in India's economy and food security. The article points out that rice and wheat occupy over half of India's arable land and are the primary sources of calories. Historically, the dramatically increased yields through high-yielding varieties, but this success relied heavily on subsidized inputs like water, electricity, and fertilizers. The current agricultural model is economically unsustainable due to soil degradation from excess fertilizers and the rising costs of inputs. To maintain food security (ensuring all people have physical, social, and economic access to sufficient, safe, and nutritious food) and economic stability for farmers, India must transition to next-generation crops. This requires significant investment in agricultural research and development (R&D) to create varieties that require fewer inputs and are resilient to climate change, thereby reducing the fiscal burden of agricultural subsidies and ensuring long-term agricultural viability.
Environmental
From an environmental perspective, the legacy of past agricultural practices poses significant challenges. The development of current wheat and rice varieties occurred without fully anticipating the ecological consequences. The heavy reliance on chemical fertilizers has led to soil degradation (loss of soil quality and fertility) and eutrophication (excessive nutrients in water bodies causing algal blooms). Furthermore, the indiscriminate use of pesticides—described in the article as using a 'metaphorical hammer'—has harmed beneficial insects and disrupted local ecosystems. The excessive extraction of groundwater for irrigation, often supported by subsidized electricity, has severely depleted aquifers in major agricultural belts. New genetic tools are essential to develop climate-resilient agriculture (farming practices that reduce vulnerability to climate change). By utilizing techniques like gene editing, scientists can develop crops that use water and nutrients more efficiently, require fewer chemical pesticides, and can withstand extreme weather events, thereby mitigating the environmental impact of farming.
Governance
The governance lens examines the regulatory environment surrounding agricultural biotechnology. The article notes that the 'shrillness of anti-GMO voices' has discouraged researchers from entering plant sciences. In India, the regulatory body for GMOs is the under the . The prolonged and often politicized approval process for GM crops (like and ) has created uncertainty for researchers and investors. This regulatory bottleneck, fueled by public skepticism, hinders the adoption of beneficial genetic technologies. Effective governance requires balancing public safety concerns with the need for technological advancement. Policymakers must foster an enabling environment for fundamental research while ensuring a transparent, science-based, and efficient regulatory framework. Promoting public awareness and science communication is crucial to counter misinformation and build public trust in new agricultural technologies.
